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 areA. `L_(2)P, RL, PQ and R_(2)Q`B. `LP, RL, PQ and RQ`C. `P_(2)L, RL, PQ and RQ_(2)`D. `LP, R_(2)L, P_(2)Q and RQ`

Answer» Correct Answer - c
Valencies of `L, Q, P and is -2, -1, +1 and +2` respectively so they will form `P_(2)L, RL, PQ and RQ_(2)`.
