Hg2O2 is called Mercury peroxide because it is composed of two mercury (Hg) atoms and two peroxide (O2) ions. The peroxide ion consists of two oxygen atoms bonded together with a single bond, giving it the -1 charge. Therefore, the correct chemical formula for this compound is Hg2O2, reflecting the presence of peroxide ions rather than dioxide ions.
