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

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Both assertion and reason are false. In case of isoelectronic, i.e., ions, having the same number of electrons and different nuclear charge, the size decreases with increase in atomic number.
