Final answer:
Element X in the compound Ba3X2 belongs to Group 2 on the periodic table, specifically the Alkaline Earth Metals. These metals readily lose both valence electrons to form compounds in which they exhibit an oxidation state of 2+. where barium is in the +2 oxidation state.
Step-by-step explanation:
Element X in the compound Ba3X2 belongs to Group 2: The Alkaline Earth Metals on the periodic table. The alkaline earth metals include beryllium, magnesium, calcium, strontium, barium, and radium. These metals readily lose both valence electrons to form compounds in which they exhibit an oxidation state of 2+. Barium, being a member of this group, reacts with other elements to form compounds such as BaCl2, where barium is in the +2 oxidation state.
