What Is Periodicity on the Periodic Table

Periodicity is one of the most fundamental aspects of the periodic table of the elements. Here is an explanation of what periodicity is and a look at the periodic properties. What Is Periodicity? Periodicity refers to the recurring trends that are seen in the element properties. These trends became apparent to Russian chemist Dmitri Mendeleev (1834–1907) when he arranged the elements in a table in order of increasing mass. Based on the properties that were displayed by the known elements, Mendeleev was able to predict where there were holes in his table, or elements yet to be discovered. The modern periodic table is very similar to Mendeleevs table, but elements today are ordered by increasing atomic number, which reflects the number of protons in an atom. There arent any undiscovered elements, although new elements can be created that have even higher numbers of protons. What Are the Periodic Properties? The periodic properties are: Ionization energy:Â  the energy required to remove an electron from an ion or gaseous atomAtomic radius: half the distance between the centers of two atoms that are touching each otherElectronegativity:Â  the measure of the ability of an atom to form a chemical bondElectron affinity: the ability of an atom to accept an electron Trends or Periodicity The periodicity of these properties follows trends as you move across a row or period of the periodic table or down a column or group: Moving Left → Right Ionization Energy IncreasesElectronegativity IncreasesAtomic Radius Decreases Moving Top → Bottom Ionization Energy DecreasesElectronegativity DecreasesAtomic Radius Increases

Stereotyping And Prejudice Of Blacks Essay - 1406 Words

Over the past few centuries, Blacks have been portrayed as â€Å"a violent underclass† (Hurwitz Peffley, 1997, p. 380). Scholars have reviewed the racial threat theory to illustrate and understand this phenomenon. It has been argued that â€Å"Whites are more supportive of punitive sanctions because they perceive an increasing threat to their economic, political, and social hegemony in the presence†¦ of large numbers of minorities† (Blalock, 1967; Mancini, Mears, Stewart, Beaver, and Pickett, 2015). The impact of stereotyping and prejudice of Blacks being perceived as threat has caused many Whites to acquire defensive and demining reactions towards Blacks. The media and society has a tendency to shy away from or almost ignore the crime of Whites and instead shift to highlight the crime of Blacks and minorities. Entman (1992) discovered during a six-month period in Chicago, news reports about Black perpetrators in violent offenses, like homicide, occurred 84% of th e time while 71% of White reported crimes were violent. Another study of a local news media reporting crime found not only that â€Å"African Americans were twice as likely as Whites to be depicted as perpetrators, 6 times more likely to be portrayed as perpetrators than as law enforcement officers, and overrepresented as criminals,† but that they also represent â€Å"close to 37% of the perpetrators depicted† while only totaling one fifth of all arrestees.

Discuss the relationship between accountability, risk management and user-centered care Free Essays

For the purpose of this TMA, I intend to look at how the use of risk management may assist and hinder practitioners accountability within the community mental health team I work in, to explore how risk management assists and hinders the relationship between social workers, employers and service users. Within the CMHT risk management is based upon guidance in Clinical Governance which states â€Å"Anticipate and prevent potential problems to learn from critical incidents and complaints and to provide systems to help clinical staff to reflect and develop their practice.† (RCN, 1998 Book 1, Chapter 9, p. We will write a custom essay sample on Discuss the relationship between accountability, risk management and user-centered care or any similar topic only for you Order Now 3). Risk assessments within the team are seen as positive tools that enable good communication between the social worker and patient. The assessment provides a basis from which a plan can be formulated to protect the patient from risk but also to extend the barriers of risk in a planned way, enabling the patient to explore and develop new coping strategies empowering them to cope with their mental illness. In these situations there is a balance to be drawn between patient’s safety and autonomy. There is however another side to the risk management processes in that practitioner’s feel â€Å"You’ve got to watch your step and cover your back! Document everything! Make sure you follow the guidelines and you keep the patient’s safe! That’s the bottom line – you’ve got to be safe. (L.Finlay, personal communication, 12 March 1999 Book 1, Chapter 9, p.187). It is this fear of punitive action that dissuades practitioners from exposing service users to avoidable risks, and risk assessments are viewed as documents providing good evidence of assessments to be accessed if ever there were questions about the care of the patient. The British Association of Social Workers gives guidelines for social workers accountability. For the purpose of this TMA accountability can be defined as â€Å"to be in a position to give an explanation for one’s actions – with reasons and justifications.† How to cite Discuss the relationship between accountability, risk management and user-centered care, Papers

Post Colonialism And the Kite Runner free essay sample

The Kite Runner takes place in Afghanistan, where conflict between the Sunni-Muslim Pashtuns and the Shiite Hazaras is very heavy. But this rivalry is not against only the Shiite Hazaras, but it includes all kinds of the Hazara people, including minorities of Sunni Hazara and Ismaili Shia Hazara. In 1747 when Afghanistan was originally founded, Pashtun had the vast majority of the state. It wasnt until the Hazaras immigrated to Kabul in the second half of the twentieth century, that their religious, ideological, economic, geographic, and linguistic characteristics were threatened. The idea of their culture being over ruled, forced the Pashtun to hate the Hazara and attempt to hinder their ways. The way the Pashtun saw the Hazara was the same way the Hazara had seen the Pashtun; wrong. If at first two people collide because of religious differences, chances are they will never get along. How can one expect others to accept their religion and way of life, when they cannot accept that of others? Being born and brought up learning a certain religion, the mind is not open to other cultures because they are given the idea that basically, what they know is correct and acceptable, while anyone who goes against it is supposedly wrong. We will write a custom essay sample on Post Colonialism And the Kite Runner or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Cultural difference is heavily focused on between the Pashtuns and the Hazaras. Throughout the novel the main character Amir is somewhat embarrassed to admit Hassan, his best friend, was a Hazara in fear of judgement. Pashtuns and Hazara have heavy conflict and the issues date back centuries before Amir and Hassans time. Pashtuns are Sunni Muslim and caucasian, while the Hazaras are Shiite Muslim and mainly asiastic, looking mongolian or chinese. The two are very easily distinguished because of the large difference simply by their appearance. It is hard to accept one another because of the many differences they have, and being raised to believe that another religion that conflicted with yours, was wrong. However, Amir was raised by Baba, an open-minded man accepting of the Hazara religion. One of Babas closest friends Ali, is the father of Hassan, is Hazara. Hazaras are often considered outsiders by other Afghans: Shiite Muslims in a mostly Sunni Muslim nation. The others or the strangers in the Kite Runner are the native Hazaras and Pashtu. The natives are being shoved out and dehumanized by the Taliban and the Russians. Taliban and Russians are attacking the natives from every angle; from attacks induced by religious differences to attacks that are simply economical and/or for the power. The reason for russians invading Afghanistan, was because the Soviet Union wanted better access to the Indian Ocean for trade and their naval fleet. Control of Afghanistan would make trade with India and the Middle East easier. Afghanistan has important natural resources such as natural gas, uranium, iron ore and copper; all which the Soviets wanted. These russians saw themselves as superior to the Afghans because they were the ones with the weapons. For example, in the Kite Runner, Baba and Amir are riding a truck to Jalalabad when a russian there on the truck requests 30 minutes with one of the Hazara women also on the ride. If it werent for Baba speaking out against such a disrespectful request, this woman would have no choice but to submit to him and follow the russians orders. Throughout the novel, punishments are given to the natives by the over-ruling Taliban. These cruel and unusual punishments make me feel upset and give me no choice but to stand against the Beard Patrol. In chapter 21, the book explains one of the Talibs games at the soccer match (p 271), The Talib, looking absurdly like a baseball pitcher on the mound, hurled the stone at the blind folded man in the hole. The man not knowing when he will be struck with the stone represents weakness to the Talib. How submissive this man is forced to be, actually excites and empowers the Talib. For a man to have fun, killing another man really disgusts me and in no way could I see a good side to the Talibs. Colonial opression is explicitly shown throughout the Kite Runner. It is easy to notice the troubled times that Afghanistan is going through. The Taliban are slowly but surely turning Afghanistan into exactly what they want; soon enough all the Hazaras will be killed off, and the Taliban will have control. Theyve already banned kite running due to kites being un-Islamic on all levels. This clearly shows an example of how the Taliban is forcing their culture and practices onto the natives. Because of the colonial opression, Afghans seek the freedom elsewhere, such as America. If the Talibans found out a Pashtun or Hazara planned to move to America, they would find it disrespectful to Afghanistan and exterminate them.
