Compared with other blocks, the ionisation energies of the transition elements are:

1. less than p-block elements
2. more than s-block elements
3. less than s-block elements
4. more than p-block elements

Correct answer: more than s-block elements

Solution

Transition elements have a higher effective nuclear charge and smaller size than the s-block metals of the same period, so their ionisation energies exceed those of s-block elements (while staying below p-block values).
