Chapter , Problem 8E(choose chapter or problem)
Consider the Lewis structure for the polyatomic oxyanion shown here, where X is an element from the third period \((N a-A r)\). By changing the overall charge, \(n\), from
\(1-\text { to } 2-\text { to } 3-\) 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 equal to zero. [Sections 8.5, 8.6, and 8.7]
