3"Mg"_ ((s)) + "N"_ (2(g)) -> "Mg"_ 3"N"_ (2(s))

Explanation:

Magnesium will react with nitrogen gas to produce magnesium nitride, "Mg"_3"N"_2, and ionic compound that consists of magnesium cations, "Mg"^(2+), and nitride anions, "N"^(3-).

The unbalanced chemical equation looks like this

"Mg"_ ((s)) + "N"_ (2(g)) -> "Mg"_ 3"N"_ (2(s))

Notice that all you need to do in order to balance this chemical equation is multiply magnesium metal by 3. This will give you a total of 3 atoms of magnesium and 2 atoms of nitrogen on both sides of the equation.

3"Mg"_ ((s)) + "N"_ (2(g)) -> "Mg"_ 3"N"_ (2(s))

This reaction is an example of a redox reaction. Here magnesium is being oxidized and nitrogen gas is being reduced.
