Question

An element X has valency of 4.write the formula for, its sulphate and chloride.

Answer 1

Given - Valency of element X

Find - Formula for its sulphate and chloride.

Solution - X sulphate will have formula X(SO4)2 and X chloride will have formula X(Cl)4.

Since the valency of an element X is four, it indicates the presence of four electrons in its outermost shell. Thus, it requires four electrons to complete its octet.

Valency of sulphate ion is -2 and chloride ion is -1.

So, X sulphate will have formula X(SO4)2 and X chloride will have formula X(Cl)4.
