Question

A sudden large jump between the values of second and third ionization energy of an element would be associated with the electronic configuration : 

(a) 1s², 2s² 2p⁶ , 3s² , 3p³ 

(b) 1s² , 2s² 2p⁶ , 3s² 

(c) 1s², 2s² 2p⁶, 3s¹ 

(d) 1s², 2s² 2p⁶, 3s² 3p¹

Answer 1

Correct option (b) 1s², 2s² 2p⁶, 3s²

Explanation:

After the removal of second electron, it will acquire stable noble gas configuration.
