✅ Answers ? Best Answer (1) Electrons in molecules and ions are associated in pairs. (There are very few “odd” molecules amongst the compounds of the main group elements; NO2, OCl2 are two examples.) (2) The shape of the molecule is determined by the number of electron pairs associated with the central atom (i.e., both … Read more
