Question

Cl⁻ ion is more stable than Cl atom - Why?

Answer 1

pls mark as brainliest

Answer 2

Cl⁻ ion is stable than Cl atom because :

Cl - Atomic number -- 17

electronic configuration : 1s² 2s² 2p⁶ 2s² 3p⁵

Valence electron - 7

valency - 1

So to attain the stability of inert gas or octet configuration, it has to accept one electron where as:

cl⁻= number of electrons = 18

so electronic configuration:1s² 2s² 2p⁶ 2s² 3p⁶

so the valence shell has attained stability as it acquired octet configuration.
