formal charges

Postby Emily Kennedy 4L » Sat Oct 27, 2018 2:56 pm

How do we know the formal charge of a transition metal since it is not given?

I believe the formal charges will either be given/shown to us in some type of way, otherwise theres a chance he may have us memorize a select few transition metals' charges beforehand.

They should write it out for you to see. Example Copper (II) sulfate, which tells you the charge of copper is +2.

formal charges show the amount of electrons that are in the valence of an electron in an atom. If the formal charge is 0 then the atom is neutral and has the same amount of electrons as protons. A negative number shows that it has that many more electrons than it normally has and a positive number would show that it has that much fewer electrons than it normally has.
