Question

electron gain enthalpy of chlorine is more negative than flurine why​

Answer 1

${\huge{\underline{\underline{\mathcal</p><p>{\green{♡Answer♡}}}}}}$

The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction.

Answer 2

Answer:

Because Cl has 3 shells and florin has 2 shells...

a as F has less Ea

1. the molecules are tightly packed an
2. even the inter electronic force is more
3. small size

And this is not only the case with F and Cl but even with other.
