The electronic configuration of four elements `L, P, Q` and `R` are given in brackets
`L (1s^(2), 2s^(2), 2p^(4)) , P (1s^(2), 2p^(6), 3s^(1))`
`Q (1s^(2), 2s^(2)2p^(6), 3s^(2)3p^(5)), R (1s^(2), 2s^(2)2p^(6), 3s^(2))`
The formula of ionic compounds that can be formed between elements are

A

`L_2 P , RL, PQ and R_2 Q`

B

`LP, RL, PQ and RQ`

C

`P_2L, RL, PQ and RQ_2`

D

`LP, R_2L , P_2 Q and RQ`

Text Solution

Verified by Experts

The correct Answer is:
C
Valencies of L, Q, P and R is -2, -1, +1 and +2 respectively so they will form `P_2 L, RL, PQ and RQ_2`.
