Consider the Lewis structure for the polyatomic oxyanion shownbelow, where X is an element from the 3rd period (Na- Ar). By changing the overall charge, n, from 1-to 2 -to 3 - we get three different polyatomic ions.
Part A: For each of these ions identify the central atom, X.
Part B: For each of these ions determine the formal charge of the centralatom, X.
Part C: For each of these ions draw a Lewis structure that makes the formalcharge on the central atom equal to zero.
Part D: For the above image, is it the correct Lewis Structure?
