Question

The electronic configuration of four element $L,P,Q$ and $R$ are given in brackets
$L(l{s}^2,2S^2,2p^4);P(l{s}^2,2s^2,2P^6,3s^1)$
$Q(l{s}^2,2s^{2}2P^6,3s^{2}3p^5)$$R(l{s}^2,2s^{2}2P^6,3s^2)$
The formulae of ionic compounds that can be formed between these elements are:

• A. $L_{2}P,RL,PQ$ and $R_{2}Q$
• B. $LP,RL,PQ$ and $RQ$
• C. $P_{2}L,RL,PQ$ and $R{Q}_2$
• D. $LP,R_{2}L,P_{2}Q$ and $RQ$

Answer 1

The correct option is C $P_{2}L,RL,PQ$ and $R{Q}_2$
