Chlorine has a charge -1. It means that X is +2 so that the formula is XCl2. Group 2 is the correct answer.

Answer;

Group 2

Explanation;

-Elements in group 2 (alkaline earth metals) have a 2 valence electrons (two electrons in the outermost energy shell). Which means that for these elements to achieve an octet configuration, they will have to loose two electrons. Therefore; element X has a valency electrons, it reacts chlorine to form a compound (XCl2), since chlorine has a valency of 1.
