Answer» Right choice is (a) Boron family Easiest explanation: The elements of the Boron family are less electropositive than the alkaline earth metals due to their smaller size and higher IONIZATION enthalpies. On moving down the GROUP, the electropositive character first increases from Boron to aluminium and then decreases from GALLIUM so THALLIUM due to the presence of d and f orbitals which causes poor shielding.
