1. well the Br part is Br- (one negative charge) so if you need 3 of them the Fe ion is the Fe3+ ion, and there is one of them. (it asks because there's also a Fe2+) since it's Fe3+ it's called Ferric bromide
as for two, i don't know

1. There is one Fe ion in iron (III) bromide.
2. There really isn't a formal name for them, but I would assume it's a polyatomic ionic compound.
