The `IP_(1), IP_(2), IP_(3), IP_(4)`, and `IP_(5)`, of an element are 7.1, 14.3, 34.5, 46.8, 162.2eV respectively. The element is likely to be

A

Na

B

Si

C

F

D

Cs

Text Solution

Verified by Experts

The correct Answer is:
B
The jump in IP value exists in `IP_5` and thus removal of fifth electron occurs from inner shell. Thus element contains four electrons in its valence shell.
