I am just beginning in chemistry and learning how to name the different molecules. I have this molecule: $\ce{PbCrO4}$.
I would give it the following name: lead(II) chromate(VI) tetraoxide. Lead and chrome have both multiple oxidation states. And as you have to specify about which ion you are speaking, it seems to me this would be the most correct name.
But this is the correct name apparently: lead(II) chromate.
Could someone please explain:
why you just specify the oxidation state for the first element and not the other? As they are both metals and both have multiple oxidation states.
why you don't say tetraoxide, although there is clearly a number 4 written?
