Question

a element 'x' has valency 2.write the formula of its sulphate

Answer 1

Answer:

carbon it has valency 2 because it two valence shell in outermost shell

Answer 2

Answer:

an element 'x' has valency 2, the formula of its sulphate would be $xSO_{4}$

Explanation:

Valency is known as the ability of an atom or molecule to bond. There are several ways to determine the valence of a particular atom. That is:

The Periodic Table consists of components organized to determine the valence of a particular element. The valence of the metal is +1 in the first column, but the valence of the noble gas is 0 in the 18th column, which is inert. The valence from the chemical formula depends on the octet rule, and the valence can be specified by examining the combination of elements.

Hence the valency of the sulphate is 2, and the given valency of element x is 2. Therefore, the compound formed would be $xSO_{4}$
