MEDIUMMCQ SINGLEIChO (Chemistry Olympiad)Inorganic Chemistryp-Block (group 13 and 14)Introduction to p-block Elements The reason behind the lower atomic radius of Ga as compared to Al is
A.poor screening effect of d-electrons for the outer✓ Correct
B.increased force of attraction of increased nuclear
C.increased ionisation enthalpy of Ga as compared to
D.anomalous behaviour of Ga.
Explanation
Poor screening effect of d-electrons for outer electrons from increased nuclear charge, Ga have smaller size than Al.
