two elements X and Y belong to the second group of periodic table.
X has 2 shells and Y has 3 shells in it
a) which of these is more metallic in nature. 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 ?
a) Y is more metallic than X since Y has more shells, it can lose electrons more easily to combine with non metals.
b) Chloride of X - XCl2
Sulphide of Y - YS
c) Since X and Y belong to the same group, they will have same no. of valence electrons in their outermost shell and have same valency, i.e. 2.
b) Chloride of X - XCl2
Sulphide of Y - YS
c) Since X and Y belong to the same group, they will have same no. of valence electrons in their outermost shell and have same valency, i.e. 2.
