- Briefly explain the following observation. S can have an expanded octet and thus SF6 exists(~$1.00 per gram), but O cannot have an expanded octet and thus OF6 does not exist as a stablecompound.(a) The ionization energy of potassium (K) is 4.34 eV and the electron affinity of chlorine (Cl) is -3.61 eV. The Madelung constant for the KCl structure is 1.748 and the distance between ions of opposite sign is 0.314 nm. On the basis of these data only, compute the cohesive energy of KCl per ion pair. (b) The observed cohesive energy of KCl is 6.42 eV per ion pair. On theassumption that the difference between this figure and that obtained in (a) is due to the exclusion principle repulsion, find the exponent n in the formula Br^-n for the potential energy arising from this source.Zinc in its 2+ oxidation state is an essential metal ion for life. Zn2+ is found bound to many proteins that are involved in biological processes, but unfortunately Zn2+ is hard to detect by common chemical methods. Therefore, scientists who are interested in studying Zn2+- containing proteins will frequently substitute Cd2+ for Zn2+ since Cd2+ is easier to detect. Based on the properties from this chapter and their positions in the periodic tables, provide one pro and one con of using Cd2+ as a Zn2+ substitute?
