Answer 2

CaCl2

Explanation:

it is made of ions and it's an ionic compound. ions can have +or- charge but the key idea is that the overall charge of an ionic compound has to balance out to be neutral.

calcium grp number 2 therefore it has 2+ charge

chlorine grp number 7 therefore it has -1 charge

as the overall charge is neutral the charge must balance so 2 cl ions to balance out the calcium ion charge

therefore it's CaCl2
