What is the valence electron configu.ration for Group SA (lS) elements?Metallic character increases when going down a group. Give some examples illustrating how Bi and Sbhave metallic characteristics not associated with N, P,and As. Elemental nitrogen exists as N2 whereas in the gas phase the elements phosphorus, arsenic, and antimony consist of P4' As4, and Sb4 molecules, respectively.Give a possible reason for" this difference between N2 and the other Group SA (lS) elements. White phosphorus is much more reactive than black or red phosphorus. Explain.
Mixing SbCl 3 and GaCl 3 in a one-to-one ratio gives a solid ionic compound of empirical formula GaSbCl 6 . A controversyerupts over whether this compound is [SbCl 2 ] + [GaCl 4 ] ─ or [GaCl 2 ] + [SbCl 4 ] ─ . It is learned that the cation in the compound has abent structure. Based on this fact, which combination is more likely to be correct? Explain.
Given a hypothetical element, X, which forms two oxides: X203 and XO2. The oxide X2O3 is a reducing agent while XO2 is an oxidizing agent. Which of the following statements best explains the chemical behavior of these oxides? a) The higher oxidation state of X in XO2 makes it a stronger reducing agent. b) The lower oxidation state of X in X2O3 indicates it donates electrons more readily, acting as a reducing agent. c) XO2 acts as a reducing agent because it has a higher oxygen content. d) The presence of more oxygen atoms in X203 makes it a better oxidizing agent.
