I'm studying electrolysis with ionic compound and the example refers to PbBr2
However, I'm confused as to why this would ever be a substance because a Pb atom has 4 electrons in its outer shell while a Br atom has 7 electrons in its outer shell. If the two Br atoms were to gain an electron each so they both have full outer shells then the Pb atom wouldn't have a full outer shell because it now has 2 electrons in its outer shell..
I thought atoms only bonded if they can get full outer shells..
