Hey dear friend here is your answer

Answer:

Valency of an element : It is the number of electrons of an atom of the element uses to combine with atoms of other elements.

It is the combining power of an atom of the element.

Valency of an atom is determined by its electronic configuration.

It gives idea about the number of electrons loss or gain in order to achieve the nearest noble gas configuration.

For example: Na(11) = 2,8,1 So, its valency is 1

Cl(17) = 2,8,7 So, its valency is also 1
