Question

correct order of electron affinity among halogens​

Answer 1

Answer:

please mark me as brainlist

Explanation:

Therefore, the correct order of electron affinity is Cl > F > Br.

Answer 2

$\huge\bold\red{Answer:-}$

• Electron gain enthalpy becomes less negative on moving down a group due to increase in atomic size. However, the electron gain enthalpy of F is less negative than that of CI due to electron-electron repulsion in small-sized F atom.

• The correct order is F<Cl>Br>I.
