Question

why is the valancy of argon 0
​

Answer 1

Answer:

yes its true.....

Explanation:

But argon is a noble gas and hence has a complete outermost shell. Thus it needs to accept or donate 0 electron to complete its octet. Hence the valency of argon is 0.

Answer 2

Answer:

Argon and Neon have 8 electrons each in their valence shells. As the elements have the maximum number of electrons in their valence shells (thereby achieving stable duplet and octet configurations), they do not have any tendency to combine with other elements. Hence, Helium, Neon, and Argon have zero valency.
