What is the correct formula for Magnesium nitride? MgNO_(3) Mg_(3)N_(2) C Mg(NO_(3))_(2) (D) D Mg_(2)N

The correct formula for Magnesium nitride is (B) $Mg_{3}N_{2}$. Magnesium has a +2 charge, while nitrogen has a -3 charge. To balance the charges, three magnesium atoms are needed for every two nitrogen atoms, resulting in the formula $Mg_{3}N_{2}$.
