Mg(MnO4)2
Magnesium permanganate is (as one would expect) made of magnesium and permanganate. The elemental abbreviation of magnesium is Mg. The chemical formula of permanganate is MnO4. Magnesium has 2 electrons in its outer shell, which gives it an overall charge of +2 (or -6). The overall charge of permanganate (MnO4) is -1, which is the same thing as +7. By the octet rule, this compound and element must combine in multiples of 8 electrons. 2+7+7=16, which is a multiple of 8. -6-1-1=-8 also works. Therefore, magnesium and permanganate will combine in a ratio of 1:2. This is expressed as Mg(MnO4)2. The parentheses are present to demonstrate that the 2 is to be distributed to everything in them. Note: The numbers should be in subscripts.
Zn(MnO4)2
Zinc normally has the +2 oxidation state in its compounds and the permanganate ion is (MnO4)-1, so one zinc and two permanganate will balance.
Zinc permanganate is Zn(MnO4)2

This doesn't really make sense. MnO4− is the symbol for a permanganate ion, however it is not a formula.
