Question: 1. Consider the Lewis structure for the polyatomic oxyanion shown here, where X is an element from the third period. By changing the overall charge, n, from -1 to -2 to -3 we get three different polyatomic ions. For each of these ions

(a) identify the central atom, X;

(b) determine the formal charge of the central atom, X;

(c) draw a Lewis structure that makes the formal charge on the central atom close to zero.
