1.	Element X forms a chloride with the formula XCI_2, which is a solid with a high melting point. X would most likely be in the same group of the Periodic Table as (a) Na (b) Mg (c) Al (d) Si
Answer» SOLUTION :As X forms the CHLORIDE with the formula `XCI_2`, it indicates that the element X is divalent. Further `XCI_2` is a solid with high melting point, it SHOWS that the chloride is ionic in nature. That further means that the element X is METALLIC in nature, such that is gives away electrons to chlorine to form the ionic chloride. These conditions are fulfilled if X is taken as Mg. Thus, OPTION (b) is correct.
