What factors affect ionisation energy and how does each of them affect it?

  1. atomic radius: the larger the atomic radius, the smaller the attraction of the outer shell electrons to the nucleus so the ionisation energy is lower reduced as atomic radius increases. 2. nuclear charge: the higher the nuclear charge the larger the nuclear attraction of the outer electrons so the ionisition energy increases. 3. electron shielding: the more inner shells of electrons therre are, the larger the shielding effect and the nuclear attraction is decreased so ionisation energy increases.
