Question

why neon has positive value of electron gain enthalpy

2marks...

Answer 1

Answer:

Neon has the highest positive electrons gain enthalpy. Explanation: On moving down the group, there is an increase in the size of atoms. As a result, the tendency to accept an additional electron decreases and hence, the electron gain enthalpy decreases from Ne to Rn.
