Question

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

• A. 1s², 2s² 2p⁶, 3s¹
• B. 1s², 2s² 2p⁶, 3s² 3p¹
• C. 1s², 2s² 2p⁶, 3s² 3p²
• D. 1s², 2s² 2p⁶, 3s²

Answer 1

The correct option is D

1s², 2s² 2p⁶, 3s²

Sudden large change in the values of I.P will be observe if noble gas configuration or stable gas configuration is reached and there is a change in the number of shells or orbits.
