The electronic configuration of

4

elements

K,L,M\,\,\mathrm{and}\,\,N

are,

\begin{array}{l} K = 1{s^2},2{s^2}2{p^1}\,\,\,\,\,L = 1{s^2},2{s^2}2{p^6}\\ M = 1{s^2},2{s^2}2{p^4}\,\,\,\,N = 1{s^2},2{s^2}2{p^3} \end{array}

The element that would form a diatomic molecule with double bond is:

View answer and explanation

Correct option: C

M

Option C (

M

) is correct because element M has the electronic configuration

1{s^2},2{s^2}2{p^4}

, meaning it needs two more electrons to complete its octet, thus forming a double bond.
