Highly innovative questions have been asked. One question from chapter 6 is given below.
Examine which one of the following is true. Illustrate your answer.
(a) “The electron affinity of dinegative ions such as O2-, S2- is also negative. This means their enthalpy of formation is positive. Such ions cannot exist except through stabilization by environment, either in a crystal lattice or by solvation in solution”…

(b) “Two and multi-charge simple anions of O are not formed: compounds containing O2- ions therefore do not exist in nature. Even in crystalline oxides of the Na2O and CaO type, the effective charge of oxygen is only about 1-“.
