Question

The ionisation energies of transition elements lie between those of ______ block and ______ block elements.

Answer 1

The ionisation energies of transition elements lie between those of s block and p block elements.

Explanation:

Transition elements have moderate ionisation energies. Their values are higher than s-block elements (which lose electrons easily) but lower than p-block elements, due to the presence of partially filled d-orbitals and increasing nuclear charge.
