Answer: The chemical formula for the given compound is [tex]Mg_3N_2[/tex]
Explanation:
Magnesium is the 12th element of the periodic table having electronic configuration of [tex][Ne]3s^2[/tex]
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 [tex][He]2s^22p^3[/tex]
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 [tex]Mg_3N_2[/tex]
