Question

Are ionisation potential and Ionisation energy same?

Answer 1

Ionisation energy is the energy required to remove the outermost electron from an isolated gaseous atom. Ionisation potential is the same as ionisation energy. Both are a measure of the energy required to remove the valence electron. The difference between the two is that while ionisation energy is expressed in kJoulemol^-1 or eV , while the ionisation potential is expressed in terms of Volts

Ionisation Potential= E/e Volts, Where E = ionisation energy and e = electronic charge
