Cu^ 2+ has a stronger polarizing power than that of Ca^ 2+ because

JEE Advanced Chemistry question

has a stronger polarizing power than that of because

(A) ion has smaller size than ion
(B) has inert gas configuration whereas ion does not
(C)Copper shows variable valency, calcium does not
(D) is smaller than ion and the d-electrons in ion shield the nucleus poorlyCorrect

Answer: (D)

Solution

() is both smaller in ionic radius than (a related but incomplete factor) and additionally has d-electrons, which shield the nuclear charge from outer electrons/approaching anions poorly compared with a noble-gas-like (, no
