Lewis dot diagrams are used to decide how atoms are arranged in compounds. Chapter 13 lewis dots for structure and shape (c&p 3rd ed. ) including organic naming. 11: we now have molecular orbitals, not the s & p atomic orbitals of individual atoms that we learned in ch. The new rule is that you can add up all the valence e-s from the p-table and distribute them wherever they need to go. : chloride, cl 1: the ion must be inside brackets with the charge outside, a negatively charged ion has more electrons, a positively charged ion has fewer electrons. Cl is a 7a element so has 7 electrons. Cl 1- has plus 1 more = 8 electrons, na + has 1 electron less: organic compounds have carbon in chains or rings, c is central carbon must form four bonds, it cannot have lone pairs.
