If the IP of Na is 5.48 eV, the ionsation potential of K will be

A

same as that of Na

B

4.34 eV

C

5.68 eV

D

10.88 eV

Text Solution

Verified by Experts

The correct Answer is:
B
Since K has larger size than `Na ` therefore its I.P. Is smaller than that Na i.e., 4.34 eV ,. Thus option ( b) is correct.
