Question

The 3D models in the following table represent ions that have their usual charge. Give the formula, including charge, and the name for each ion. The second question.

Answer 1

The molecule is composed of phosphorus (P) and oxygen (O).

The Lewis structure is:

It is observed that each oxygen has a formal charge of -1, therefore the ion has a total charge of -3.
