The Factors Affecting Ionisation Enthalpy…

The Factors Affecting Ionisation Enthalpy –
(i) IE decreases as the size of the atom increases.
(ii) IE increases with increase in nuclear charge.
(iii) The most important factor that affects ionisation enthalpy is size.
(iv) Effective Nuclear charge is directly proportional to nuclear charge.
(v) IE decreases with increase in shielding effect or screening effect.
