If the overall charge of a Lewis Structure is -1, does that mean all the atoms' charges are adding to -1?

So for ions, do the formal charges need to equal the charge of the whole molecule?

Yes, if you are drawing a Lewis structure for an ion, the sum of all of the formal charges in the ion must equal the total charge of the ion.

Yes, they should all add up to -1. The individual charges can vary so long as the entire molecule's overall charge matches the given charge. But you must also keep in mind that the individual charges should be the lowest that they can be.

Yes! The molecule will have an overall charge of -1, so each atom will have its own charge (likely -2 and +1) allowing the whole molecule to add to -1.

Yes because the formal charges have to add/subtract to -1.
