A sudden large jump between the value of second and third ionization energies of an el,ement would be associated with which of the following electronic configuration?

Options

A. `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^(1) 3p^(2)`
D. `1s^(2)2s^(2)2p^(6)3s^(2)`

Answer

D

Explanation

Sudden jump from `IE_(2)to IE_(3)` is given by elements which attain stable configuration of noble gas after losing 2 electrons.
