MCQ

Assertion (A): In case of isoelectronic ions the ionic size increases with the increase in atomic number.
Reason (R): The greater the attraction of nucleus, greater is the ionic radius.

A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
✓
A is false but R is true.

✓

Answer

Correct option: D.

A is false but R is true.

(d) Both A and R are false.
Explanation: In case of isoelectronic ions, i.e., ions, having the same number of electrons and different nuclear charge, the size decreases with increase in atomic number.
