ચાર તત્વો L, P, Q અને Rનું ઇલેક્ટ્રોનિક રૂપરેખા L (1s^(2), 2s^... કૌંસમાં આપવામાં આવ્યું છે.

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

L/Q & L/(Q)power 1/2
