Okay correct and you've said that one of the products is magnesium oxide. What elements make up a nitrate ion? (There are two)

Look at the numbers you have in front of the O2 and NO2. You have to make sure both sides of the equation are balanced.

Start by balancing the nitrogen atoms on both sides.

No, look at 2Mg(NO3)2, how many nitrogens are in there?

Here you go:
2 Mg(NO3)2 → 2 MgO + 4 NO2 + O2
