WebThe ionization energy is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. (1) H ( g) → H + ( g) + e −. This energy is usually expressed in kJ/mol, or the amount of energy it takes for all the atoms in a mole to lose one electron each. WebThe ionization enthalpy of an element can be defined as the amount of energy required to remove an electron from an isolated gaseous atom in its gaseous state. Ionization enthalpy depends on the following factors: Penetration effect Shielding effect Electronic configuration 1. Penetration Effect

Ionisation enthalpy decreases from Boron to Aluminium, increases to Gallium, decreases to Indium and again increases to Thallium. This inconsistency can be attributed to the poor screening effect of d and f orbits of the elements. WebIonisation enthalpy of the group 13 elements is not regular. Here is the order of the first IE of these elements- B > Tl > Ga > Al > In This irregular trend is attributed to d-block and f-block contraction.
