In the 13th group, or the boron group, the inert pair effect refers to the tendency of the heavier elements (such as gallium, indium, and thallium) to preferentially lose their outer s-electrons before the d-electrons, resulting in a lower oxidation state than expected based on their group number. This can be attributed to the poor shielding of the d-orbitals from the increasing nuclear charge, making it energetically more favorable for the s-electrons to be lost first.
