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_2P,RL` ,PQ and `R_(2)Q`B. `LP,RL,PQ` and RQC. `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 R is -2,-1,+1 and +2 respectively and one electron in their outermost shell so they will form cation easily. |
