Which of the following configurations is associated with biggest jump between second and third I.E.?

Answer»

`1S^(2)2s^(2)2P^(2)`
`1s^(2)2s^(2)2p^(6)3s^(1)`
`1s^(2)2s^(2)2p^(6)3s^(2)`
`1s^(2)2s^(2)2p^(1)`

SOLUTION :After the loss of TWOELECTRONS, the ION acquires the stable electronic configuration of noble gas `[2s^(2)2p^(6)]`
