when the elements mg and cl form an ionic bond, mg loses electron(s) from the 3s orbital to form the mg2 cation. cl gains electron(s) in the 3p orbital to form the cl– anion. since the total number of electrons lost always equals the total number of electrons gained, the compound formed will contain mg2 ions) for every cl– ion(s). fill in the blanks with the appropriate numbers.
