Question

Give reason for the following:

Argon atom is bigger than chlorine atom. 

Short/Brief Note

Solution

Since Argon has stable octet configuration, so due to the inter- electronic repulsions the effect of nuclear pull over the valence shell electrons cannot be seen which results in the bigger size.
