A sudden large jump between the values of second and third ionisation energies of an element would be associated with the electronic configurationA. `1S^(2)2s^(2)2p^(6)3s^(1)`B. `1S^(2)2s^(2)2p^(6)3s^(2)3p^(1)`C. `1S^(2)2s^(2)2p^(6)3s^(2)3p^(2)`D. `1S^(2)2s^(2)2p^(6)3s^(2)`

Answer» Correct Answer - D
A sudden large jump between the values of second and third ioniation energies of an element woluld be associated with elements of group 2 or alkaline earth metals with valence shell electronic configuration of `ns^2`
