Two elements ‗x‘ and ‗y‘ belong to the second group of the periodic table. ‗x‘ has 2 shells and ‗y‘ has 3 shells in it –
a.which of these is more metallic in nature and why?
b.what is the formula of the chloride of ‗x‘ and sulphide of ‗y‘?
c.is the valency of ‗x‘ same as that of ‗y‘ or different? why?

hey buddy,
a) Y is more metallic
reason: Electropositivity is directly proportional to metallic character
as size of the atom increases, electropositivity increases
b) formula of chloride- xcl2
formula of sulphide-ySO4
c) their valency is same becz
in a grp, all the elements hav same no of valance electrons

Explanation:
(a) Y is more metallic in nature as metallic nature increases down the group.
(b) Both x and y has a valency of 2 so chloride of x is XCl2 and sulphide of y is YS
(c) The valency of x and y is same as they lie in the same group no.
