The electronic configuration of four ato...

The electronic configuration of four atoms are given in brackets :
`L(1s^(2)2s^(2)2p^(1))," "M(1s^(2)2s^(2)2p^(5)),`
`Q(1s^(2)2s^(2)2p^(6)3s^(1))," "R(1s^(2)2s^(2)2p^(2)),`
The element that would most readily form a diatomic molecule is

A

Q

B

M

C

R

D

L

Text Solution

Verified by Experts

The correct Answer is:
B
By sharing of 1 electron each, both atoms of M will get a completed octet.
