Should we be taking the formal charge every time we do a Lewis Structure? Or is that only when specifically asked in the question?

It is a useful check to determine if structure is correct.

During my review session students asked about alternative structures and I used formal charge.

When I ask in an exam question to give FC or show it is the lowest energy structure then FC definitely needed.
