However, in the case of lead (Pb), the ionisation energy is higher than that of tin (Sn) due to inadequate shielding of the inner f-orbitals. This results in a greater effective nuclear charge experienced by the outer shell electrons in lead.
Ionisation energy, measured in kilojoules per mole (kJ mol-1) The user's text is simply \"C\". Chemical elements Si, Ge, Sn, and Pb have corresponding values for IE1 and IE2 as follows: IE1: Si - 1086, Ge - 786, Sn - 761, Pb - 708, IE2: Si - 2352, Ge - 1577, Sn - 1537, Pb - 1411.(ii) The ionisation energies of group 14 elements are greater than those of their corresponding group 13 elements due to their smaller size.(iii) The electropositive nature of these elements intensifies as we move down the group due to a reduction in ionisation energy.
Group 4 elements exhibit a discernible pattern in their ionisation energy trend. The ionisation energy typically decreases as one descends a group in the periodic table. The reason for this is that the atomic radius expands as one descends a group, resulting in the electrons being positioned at a greater distance from the nucleus. Consequently, a reduced amount of energy is needed to extract an electron from the outermost shell, resulting in decreased ionisation energies.\n
