The correct order of increasing radii of...

The correct order of increasing radii of the elements`Si,Al,Na and P` is

A

`Si, Al, P, Na`

B

`P, Si, Al, Na`

C

`Al, Si, P, Na`

D

`Al, P, Si, Na`

Text Solution

Verified by Experts

The correct Answer is:
B
Due to half-filled orbitals in `P` so that radius of `P` small than `Si`
`P, Si, Al, Na`.
