Question

Explain ionization potential decreases from top to bottom in a group​

Answer 1

Answer:

sorry I am not available

Answer 2

Answer:

It is due to shielding by electrons.

Explanation:

As we go down the group, the electrons are added to outermost shell or valence shell. These electrons are shielded from the attraction of nucleus by inner electrons. Hence, energy required to remove the loosely bound electron as we move down the group decreases, that is, ionization potential decreases.
