Vedclass · Answer

(D) large difference between the second and third ionization energy ($IE_2$ and $IE_3$) indicates that the element has two valence electrons,such that removing the third electron requires breaking a stable noble gas configuration.For the configuration $1s^2 2s^2 2p^6 3s^2$:$1s^2 2s^2 2p^6 3s^2$ $\xrightarrow{IE_1} 1s^2 2s^2 2p^6 3s^1$ $\xrightarrow{IE_2} 1s^2 2s^2 2p^6$ $\xrightarrow{IE_3} 1s^2 2s^2 2p^5$After losing two electrons,the element achieves a stable noble gas configuration $(1s^2 2s^2 2p^6)$. Removing the third electron from this stable shell requires a significantly higher amount of energy.

In which of the following electronic configurations of an element is there a very large difference between the second and third ionization energy?
