Question

argon an atom has 8 electrons in its valence shell but its valency is not 8. explain.​

Answer 1

Explanation:

Both Argon and Neon have 8 electrons in their outermost or their valence shells. It means their octet is complete. As their octets are complete, these elements do not have a tendency to gain or lose any electron. They do not tend to combine with other elements

Answer 2

Valency is the number of electrons lost, gained or shared by an atom. Valency is 4 max and 8 is impossible.

Argon is an inert gas having fulfilled octet to become stable. So, valency of argon is 0.
