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 :`X 1s^(2) 2s^(2) 2p^3` So it is NITROGEN atom and its valency = 5,3 Mg is in SECOND group, So its valency = 2 ` therefore `Formula will be `Mg_3N_2`
