Question

Why do some element show variable valency.​

Answer 1

Explanation:

Some elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency.

Answer 2

Answer:

The electrons which are present in an atom's outermost shell are called valence electrons. Such elements therefore indicate two or more different valencies i.e. they have variable valentia.
