Ionisation enthalpy of group 13 elements
WebIonisation Enthalpy: We have already learnt that as we move down a group, generally there is a steady decrease in ionisation enthalpy of elements due to increase in their atomic radius. In p-block elements, there are some minor deviations to this general trend. In group 13, from boron to aluminium the ionisation enthalpy decreases as expected. WebChemistry Specification Checklist.
