Vedclass · Answer

(A) $d-$block elements have higher ionisation potential values compared to $f-$block elements. This is because the $f-$orbitals have poor shielding effect,which leads to a higher effective nuclear charge experienced by the valence electrons in $f-$block elements. However,the question asks for the comparison of $d-$block relative to $f-$block,and since $f-$block electrons are more shielded from the nucleus by inner shells,they are held less tightly than $d-$block electrons in corresponding periods. Therefore,the ionisation potential of $d-$block elements is higher.
