Four elements P,Q,R & S have ground state electronic configuration as:
`{:(P rarr 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(3),Q rarr 1s^(2) 2s^(2)2p^(6)3s^(2)3p^(1)),(R rarr 1s^(2) 2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(3),S rarr 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(1)):}`
Comment which of the following option represent the correct order of true (T) & false (F) statement I size of `P lt` size of Q
II size of `R lt` size of S
III size of `P lt` size of R (appreciable difference)
IV size of `Q lt` size of S (appreciable difference)
