JEE Main Chemistry question

Statement 1: Isoelectronic species are having same number of electrons but different radii. Statement 2: Higher the charge, smaller the ion.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is FalseCorrect
(D)Assertion is False, Reason is True

Answer: (C)

Solution

Isoelectronic species do indeed share the same electron count yet differ in radius, so the Assertion is true. The Reason as stated ("higher the charge, smaller the ion") is imprecise: what actually governs the radius of isoelectronic species is the
