The electronic configuration of four elements

L,P,Q

and

R

are given in brackets

L\left( {1{s^2},2{s^2},2{p^4}} \right),P\left( {1{s^2},2{s^2},2{p^6},3{s^1}} \right),Q\left( {1{s^2},2{s^2},2{p^6},3{s^2},3{p^5}} \right),R\left( {1{s^2},2{s^2},2{p^6},3{s^2}} \right)

The formula of ionic compounds that can be formed between these elements are

View answer and explanation

Correct option: C

{P_2}L,RL,PQ

and

R{Q_2}

Option C (

{P_2}L,RL,PQ

and

R{Q_2}

) is correct because it correctly predicts the ionic compounds formed based on the electronic configurations and valencies of the elements.
