MCQ
Which of the following electronic configuration is associated with the biggest jump between the second and third ionization energies?
- A$1s^2 \,2s^2 \,2p^2$
- B$1s^2 \,2s^2\, 2p^6\, 3s^1$
- ✓$1s^2 \,2s^2 \,2p^6 \,3s^2$
- D$1s^2 \,2s^2 \,2p^1$
A) $1 s\, 2 s$
B) $1 s ^2 \,2 s ^2 \,2 p$
C) $1 s^2\, 2 s^2 \,2 p^5$
D) $1 s ^2 \,2 s ^2 2 p^6$
From the options above we notice that the greatest energy will be involved for option $C$ as it has attained the noble gas configuration after the loss of $2$ electrons and removal of a $3$ electron will require a lot of energy.
