Explanation:
3 Factors Affecting Ionisation Energy
1.Size of the positive nuclear charge. As the nuclear charge increases, its attraction for the outermost electron increases and more energy is required to remove an electron. ...
2.Size of atom (distance of outermost electron from the nucleus) ...
3.Screening (shielding) effect of inner shell electrons.

Factors affecting ionisation potential :
: Larger the atomic size, smaller is the ionisation potential. It is due to that the size of atom increases the outermost electrons e farther away from the nucleus and nucleus loses the attraction on that electrons and hence can be easily removed.
: Ionisation potential increases with the increase in nuclear charge between outermost electrons and nucleus.
Screening effect : Higher is the screening effect on the outer most electrons causes less attraction from the nucleus and can be easily removed, which is leading to the lower value of ionisation potential. Penetration power of sub shells and Stability of half filled and fully filled orbitals.
