You break it up into magnesium(Mg) and nitrate(NO3). They are ions with the charges Mg2+ and (NO3 )1- . To make the formula, their charges must be balanced at 0. Therefore, the formula is Mg(NO3)2
Mg(NO2)2 is an ionic compound. The formula MG(NO2)2 is the formula for the ionic compound of Magnesium Nitrite trihydrate
magnesium oxide + nitrogen >>> magnesium nitrite
ionic and it's magnesium nitride
Mg(NO2)2 + 2NaOH --> Mg(OH)2 + 2NaNO2
The chemical formula of ammonium nitrite is NH4NO2; the molecular mass is 64,06 grams.

KMnO4 + NaNO2 -> KNO2 + NaMnO4
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
It is made up of copper , cadmium , lead , magnesium , sodium , manganese , zinc , nitrate and nitrite.
The chemical symbol for potassium nitrate is potassium. "KNO3"
