Answer: The chemical formula for the given compound is \(Mg_3N_2\)
Explanation:
Magnesium is the 12th element of the periodic table having electronic configuration of \([Ne]3s^2\)
This element will loose 2 electrons and form an oxidation state of +2 units.
Nitrogen is the 7th element of the periodic table having electronic configuration of \([He]2s^22p^3\)
This element requires 3 electrons and thus shows an oxidation state of -3 units.
By criss-cross method, the oxidation state of the ions gets exchanged and this form the subscripts of the other ions. It results in the formation of a neutral compound.
Thus, the chemical formula for the given compound is \(Mg_3N_2\)
