polyatomic ions). 1. Determine the Number of valence electrons in the Lewis Structure: One of the easiest ways to start drawing a Lewis Structure is to make a list of each atom in the structure and next to each atom record how many valence electrons it has and how many it needs to fill its valence shell.

Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying
