What the Numbers on the Periodic Table Mean

What the Numbers on the Periodic Table Mean Are you confused by all the numbers on a periodic table? Heres a look at what they mean and where to find important numbers on the table.   Element Atomic Number One number you will find on all periodic tables is the atomic number for each element. This is the number of protons in the element, which defines its identity. How to Identify It: There isnt a standard layout for an element cell, so you need to identify the location of each important number for the specific table. The atomic number is easy because it is an integer that increases as you move from left to right across the table. The lowest atomic number is 1 (hydrogen), while the highest atomic number is 118. Examples: The atomic number of the first element, hydrogen, is 1. The atomic number of copper is 29. Element Atomic Mass or Atomic Weight Most periodic tables include a value for atomic mass (also called atomic weight) on each element tile. For a single atom of an element, this would be a whole number, adding the number of protons, neutrons, and electrons together for the atom. However, the value given in the periodic table is an average of the mass of all isotopes of a given element. While the number of electrons does not contribute significant mass to an atom, isotopes have differing numbers of neutrons, which do affect mass. How to Identify It: The atomic mass is a decimal number. The number of significant figures varies from one table to another. Its common to list values to two or four decimal places. Also, the atomic mass is recalculated from time to time, so this value may change slightly for elements on a recent table compared with an older version. Examples: The atomic mass of hydrogen is 1.01 or 1.0079. The atomic mass of nickel is 58.69 or 58.6934. Element Group Many periodic tables list numbers for element groups, which are columns of the periodic table. The elements in a group share the same number of valence electrons and thus many common chemical and physical properties. However, there wasnt always a standard method of numbering groups, so this can be confusing when consulting older tables. How to Identify It: The number for the element group is cited above the top element of each column. The element group values are integers running from 1 to 18. Examples: Hydrogen belongs to element group 1. Beryllium is the first element in group 2. Helium is the first element in group 18. Element Period The rows of the periodic table are called periods. Most periodic tables do not number them  because they are fairly obvious, but some tables  do. The period indicates the highest energy level attained by electrons of an atom of the element in the ground state. How to Identify It: Period numbers are located on the left-hand side of the table. These are simple integer numbers. Examples: The row starting with hydrogen is 1. The row starting with lithium is 2. Electron Configuration Some periodic tables list the electron configuration of an atom of the element, usually written in shorthand notation to conserve space. Most tables omit this value because it takes up a lot of room. How to Identify It: This isnt a simple number but includes the orbitals. Examples: The electron configuration for hydrogen is 1s1. Other Information on the Periodic Table The periodic table includes other information besides numbers. Now that you know what the numbers mean, you can learn how to predict periodicity of element properties and how to use the periodic table in calculations.

Should Juvenile offenders be tried as adults Essay

Should Juvenile offenders be tried as adults - Essay Example e recent past, many young people in the early 20s have faced police arrests because they have violated the law in various ways by committing criminal offenses. Many arguments have been raised over the manner in which the state has been handling juvenile offenses (Bradley 135), with some saying that those juvenile courts and justice systems should be abolished and juvenile delinquents tried as adults. Rapists, murderers and other types of law offenders are being let to walk freely from jails after having served lenient and short sentences. These criminal offenders are children, who in most cases have not attained the necessary statutory age to face trial as adult members of the society. Juvenile delinquents often benefit from juvenile rights and court systems that emphasize that these groups of criminals need to be given second opportunities to reform and become useful members of the society. This has been making these minors enjoy freedom, walking freely in the streets and neighborhoods while committing extra crimes. For this reason, many people have been advocating the abolishing of juvenile rights and court systems so that these law offenders are tried and made to serve their sentences as adult members of the society. These people centre their arguments on the fact that giving stiff sentences and penalties to these minors is essential in preventing future offences. One of the arguments given in support of these claim is that the juvenile court systems is established on many false premises due to its purpose to prevent youths from the alleged consequences of their actions. For instance, young people that are released from these juvenile jails often end up engaging in repeat offenses, something that underlies the fact that the juvenile systems do not live to their expectations as reliable correctional facilities. Additionally, juvenile courts have been blamed for their inability to prevent juvenile violence. Abolishment of juvenile legal systems often requires

VLAN Network Security Research Paper Example | Topics and Well Written Essays - 2000 words

VLAN Network Security - Research Paper Example Although, VLAN 1 simplifies the installation process of the switch significantly, it also makes the network vulnerable to unauthorized access (Liska, 2003). To improve security on switches, Liska (2003) suggested that the default VLAN should be removed, and each port on the switch should be added to the appropriate VLAN (P.S. Empty ports should be configured with no VLAN). In case if the switch does not allow removal of the default VLAN, then the active ports on the switch should be switched to different VLAN. Liska (2003) further emphasized that the port which is connected to the upstream switch or router should be removed from the default VLAN because it is tagged with all of the VLANs, and therefore, it can provide a gateway to all the traffic on the network if an attacker is successful in determining the default VLAN for the tagged port. The OSI model is based on layered model in which the communication protocol divides its functionality into a series of layers. Each layer provides services to its subsequent, upper layer, and requires services from its preceding, lower layer. However, each layer is isolated from other layers and operates independently to perform a subset of functions. Although, the layer independence provides interoperability and interconnectivity, it also causes security risks because if any layer is compromised, then other layers remain unaware of this (Wong & Yeung, 2009). In OSI model, the Data Link Layer (Layer 2) is very crucial because all the upper layers rely on it to provide the reliable data transfer across physical link – if this layer is compromised, then the entire communication session is compromised. Therefore, it is extremely important to secure this layer and take appropriate measures to mitigate attacks on this layer (Wong & Yeung, 2009). VLAN-based networks are vulnerable to various attacks. Many of these attacks can be initiated by those with the LAN access, from outside the switch.

Samsung Quality Issue Management

Samsung Quality Issue Management Harsh Yadav   REFLECTION SAMSUNG NOTE 7 (QUALITY ISSUE) Introduction Samsung is one of the leading technology giants around the globe encompassing numerous business sectors like electronics, construction, life insurance, etc. in its portfolio. With its headquarters in Seoul, Samsung Electronics, one the various affiliates of Samsung group has been able to retain highest market share (21% 23%) in smartphone business in the past couple years, beating its major competitor Apple by a huge margin of around 9% (International Data Corporation, 2016). On 19th August, 2016, Samsung released its latest smartphone model named Samsung Galaxy Note 7. Considering the success of its previous versions, Note 7 was supposed to be a major competition for its rival iPhone. Unfortunately, within 2 months of its release, Samsung had to discontinue its manufacturing in October 2016 due to some quality issues with its battery, as there were many cases reported where the battery suddenly caught fire. Impact It was a huge blow on Samsungs brand image as its latest smartphone release was facing major quality issues. This not only affected the companys reputation but also raised the fingers on its research and development department, which is known for its innovative designs. Moreover, this issue was putting the safety of the Note 7 customers at a huge risk. According to the United States Consumer Product Safety Commission, around 90 incidents of battery overheating were reported along with 55 incidents of property damage and 26 incidents of burns in the US, all due to Samsung Note 7 (Chen Sang-Hun, 2016). Samsungs next step For damage control, Samsung had to recall its 2.5 million released Note 7 handsets (Mozur Lee, 2016). In its official statement, Samsung requested the customers to get their devices replaced at nearest Samsung store for a safer Note 7 device. As it was the worst quarter of a year for Samsung in past few years, the replacement sets also started facing the same issues and the company had no other choice but to order for the second recall for all the available Note7 devices in the market, including the so called safer replacement devices. The company assigned two separate teams for investigating the root cause of the problem. Ultimately in October, 2016, Samsung officially discontinued producing Note 7 handsets, incurring a loss of around $17 billion in lost sales from its expected sales of around 19 million units (Carlon, 2016). Root Cause After this tremendous mishap, Samsung sent a report to KATS (Korean Agency for Technology and Standards) explaining the reasons for this quality control issue which was originally due to a defect in their Note 7 design (Hollister, 2016). In Lithium ion batteries used in smartphones, there is a thin plastic layer that separates the positive and negative poles which need to be insulated from each other in order to avoid short circuit causing overheating of the battery and eventually fire. The design of the phone was such that it was putting a lot of pressure on the battery which led the plastic layer to get punctured and hence the short circuit. This defect was revealed while revising the assembly process of the phone (Hollister, 2016), which had to be done for Quality Management purpose. This was the reason which didnt allow the companys corrective action of changing the Note 7s batteries and sending them as safer replacements, to succeed. Samsung refunded the customers and learned some lessons from this mistake and also made critical improvements in its quality control process. This had to be done to maintain customer relationship. One of the contributing factors for this quality failure was the time factor from triple constraints, as Samsung was in a rush to beat iPhone 7, which hampered the quality considerations in Note 7s design. This also forced the company to re-evaluate every process in its product development cycle (Kovach, 2016).Also, due to the time constraint only Samsung had to stop Note 7s production and concentrate on it next model, otherwise they could have found out the problem and correct it.

Categorical imperative Essay

Philosophers usually tend to think and respond in totally different and opposite ways. However, in Glaucon’s challenge, Aristotle, Spinoza, Hume, Kant and Mill agreed that it’s an uncontrollable system of desire. In Glaucon’s challenge he describes three important ideas. The first idea is â€Å"of the nature and origin of unjust, according to the common view of them† (488). The second idea is â€Å"I will show that all men who practice justice do so against their will, of necessity but not as a good† (488). The third idea is â€Å"I will argue that there is reason in this view, for the life of the unjust is after all better far than the life of the just† (488). Each one of these philosophers responded to this challenge similar and different manners. Aristotle believed that to be a good man is to have good morality. In his point of view he sees that morality gives a reason that leads to actions. Artistotle respond toward Glaucon’s challenge is reason guides passion. This makes him an injustice man because he just cares about how to please himself and follow his desire. Spinoza’s idea is emotions have nothing to do with human beings its reasons that guide us. He believed that passion and emotions leads us to be changeable due to how the world around us and not necessarily our knowledge. Reasons give us the opportunity to gain knowledge of life. Spinoza becomes unjust and gives reasons to Glaucon’s challenge. From Hume’s point of view he believed that benevolence makes us social being instead of self interest. Hume’s main concern is sympathy and empathy. Sympathy is the nature of human that makes them human beings. It’s the ability to see feel pity toward other. Empathy is the understanding of pain and happiness of one another. Hume believed that all human are selfish and that their passion guides their reasons. Passion and reasons is not having emotions or feeling pity. Hume’s view is that we should the ability to feel others emotions and understand them. Kant sees that the categorical imperative is the only moral way to act. Categorical imperatives are based on ideals of logic and acts on duty. He believed that if you feel satisfied about something you did, you shouldn’t consider it a reward but rather as a bonus for you. We only do moral things because it’s in fulfill our interest and benefit. Kant responds to Glaucon’s challenge that if the act is immoral, then it cannot be considered into categorical imperative. Mill’s view is that everyone should be satisfied and happy. He believes that everyone should think of the consequences of their actions before deciding to make them. Mill puts others as well as himself into consideration before any action. He doesn’t argue towards or against Glaucon’s challenge, he just cares about his pleasure and others. Each philosopher had his own argument toward Glaucon’s challenge. Their ideas were unjust happiness towards Glaucon’s challenge. Aristotle and Hume had opposite views. Aristotle‘s idea towards the challenge was reason guides passion, where Hume’s idea was passion guides reason. Mill and Kant had the same assumptions. Mill expresses about pleasure and Kant was certain about duty. Mill agrees with Aristotle as well, they believe that happiness is a man’s ambition and human existence. Spinoza is just unjust to the whole idea of the challenge. These philosophers’ ideas were very similar that a man would behave unjust if he had the ring.

Summary Of If You Give A Mouse A Muffin - 980 Words

1. Running Records- Starting on my third visit I started to keep running records of Jimmy’s reading. I collected three samples of his reading to be able to really asses his reading using miscue analysis and his CWPM (correct words per minute) and his WPM (words per minute). The first book that Jimmy selected was an AR book that was titled â€Å"War of the Worlds†. Based off of the AR guidelines it was a 3.2 reading level. This means third grade second six weeks. The next two samples were from a book that I selected. That book was titled â€Å"If You Give a Mouse a Muffin†. The AR reading level for this book was 2.4 which means second grade 4th six weeks. You will notice that the reading level of these books jumps drastically I did this because he struggled with the book that he selected that was at a higher level. This hurt his fluency, CWPM, WPM, and comprehension. I will discuss each of these in detail in different sections. One of my suggestions is that he work on books at a low er level to really build a prior knowledge in vocabulary, work on fluency, and his CWPM, and WPM which the running records show.
