32. The first ionisation energy of gallium is greater than that of aluminum and the first ionisation energy of thallium is greater than that of indium. What could be the possible explanation for this? A. This is the normal trend in ionisation energy. B. Both Ga and Tl prefer to lose three electrons rather than one. C. Both Ga and Tl follow transition elements which are excellent shielders of nuclear charge. D. Ga follows a series of transition elements and TI follows both a series of transition elements and inner transition elements which are poor shielders of nuclear charge.
