The electronic configurations of four elements L,P,Q and R are given below,

L = 1{s^2},2{s^2}2{p^4}\;\;\;Q = 1{s^2},2{s^2}2{p^6},3{s^2}3{p^5}

P = 1{s^2},2{s^2}2{p^6},3{s^1}\;\;\;R = 1{s^2},2{s^2}2{p^6},3{s^2}

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

View answer and explanation

Correct option: C

{P_2}L,\;RL,\;PQ,\;R{Q_2}

Option C (

{P_2}L,\;RL,\;PQ,\;R{Q_2}

) is correct because it represents the correct ionic formulas based on the valencies of the elements L, P, Q, and R.
