1.	Magnesium reacts with an element (X) to form an ionic compound. If the ground state electronic configuration of (X) is 1s^2 2s^2 2p^3 the simplest formula for this compound is-
Answer» `Mg_3X_2` `Mg_2X_3` `Mg_2X` `MgX_2` SOLUTION :ELECTRONIC configuration of X: `1s^2 2s^2 2p^3` `:.` Valency of X = 3 Here, valency of MG = 2 Thus the COMPOUND will be `Mg_3X_2`.
