What are the charges of the elements in the d- block of the periodic table?

Question

i'm supposed to know the charges of the monatomic ions for AP chem but i can't find the charges for the ones in the middle. is it because the charge changes...idk???!!!!

Answer 1

They range from 1+ to 7+ depending on the oxidation state.

There's not a good rhyme or reason to it, except that the metals left of iron can have a charge up to their group number (6+ for chromium, 7+ for manganese).  Iron, cobalt, and nickel are almost always 2+ or 3+.  Group 11/IB are 1+, but copper also has a 2+ and gold also has a 3+.  Group 12/IIB are all 2+, except mercury also has a diatomic ion Hg2 that is 2+ for an effective 1+ on both atoms.
