Halogensand Noble Gases

Groupsin the periodic table refer to the families in which elements withsimilar characteristics are displayed .in the given context I chosenoble gases and halogens which are placed just next to each other asgroup 18 and 17 respectively. This implies that elements with thesame chemical and physical properties fit in the same family.

Presentedas group 17, halogen consists of chlorine, bromine and iodineelements. Halogens are highly reactive and they exist inform ofmolecules that usually bond covalently. During reaction, theseelements produce vapor that is usually colored. Chlorine forms greenvapor, bromine forms a red vapor whereas iodine produces purplevapor. Additionally, halogens have weak intermolecular forces and asa result, they have low boiling and melting points. Elements in thisgroup easily form compounds. For instance, when chlorine reacts withsodium the resulting compound is sodium chloride. Similarly, brominereaction with sodium will lead to the formation of sodium bromide.

Noblegases occur as group 18 in the periodic table. This group is made upof radon, xenon, krypton, neon and helium. Notable features that makeelements in this group similar are their inability to react,resistance to form compounds and their colorless odorless nature. Itshould be noted that noble gases will display these characteristicsunder standard conditions. Moreover these elements n awfully highpotential for ionization .their oxidation number of 0 prevents theseelements from readily reacting. This means that they are inert andare therefore suitable in applications where reactions are notneeded.

Thefictitious element in this case is metal B,which has an atomic mass of 26.the atomic structure of this elementis thus The outer shell of element Bis already full and therefore the element has a valency of 0 makingit unable to react. Therefore, this element fits in the group ofnoble gases.

Part 1

The author which I relate this week’s lesson is John Oskison. Inhis poem, the writer clearly demonstrates his opinion in a clear andunderstandable way. John Oskison is a poet born in Vinita in India.His interesting short narrative “The problem of Old Harjo” waspublished in 2006. In this narrative, he explains the challenges of ayoung missionary who makes the effort of negotiating the disputebetween a director of the Indian mission and a then to be Creekconvert. Harjo is inspired by the young missionary and decides tojoin Christianity. However, a condition is provided that he must giveup his two wives. Through the narrative of the problems experiencedby Harjo, John Oskison clearly brings out the themes of religion andfaith, community identity, ethnicity, culture and race.

Part II

“why I write” byJoan Didion and Wallace Stevens’ “A Postcard from the Volcano” both have their root in the American literature since the civil war.Thus, away describe the American culture. In both these poems, thenarrators use the same strategic approach to present their themes inthe poem. Wallace Stevens narrates how the sky cries out of “literatedespair” to the new generation because the dead have spoken whileJoan Didion displays her unique style to explain why she became awriter. The authors are situated in different setting thus they havea different opinion.

Part II

The old Harjohappens to have two wives. Interestingly, in his Christian community,men are prohibited from marrying more than one wife. In thisnarrative, Harjo is faced with a dilemma of blending his new beliefswith the ones in the society. Also, John Oskison brings out the themeof religion by placing Harjo in the complex situation of not knowingwhich belief to uphold his ancestral or cultural belief or his newfound belief. These dilemmas make the audience view Harjo aspowerless as he is practically and psychologically propelled fromboth sides of his dilemma. The only solution Harjo has is to foregoone belief for the other.
