Question

In a group with the increase in atomic number ionization enthalpy value decreases due to which factors ? Explain it .​

Answer 1

Answer:

good

Explanation:

Due to the increase in size the distance of the electron from the nucleus increases and force of attraction between the nucleus and the valence electron decreases. So, the energy required to remove valence electrons will be less and they can be easily removed. Thus the ionization energy decreases down the group.

Answer 2

Explanation:

Due to the increase in size the distance of the electron from the nucleus increases and force of attraction between the nucleus and the valence electron decreases. So, the energy required to remove valence electrons will be less and they can be easily removed. Thus the ionization energy decreases down the group
