Vedclass · Accepted Answer

$1s^2 2s^2 2p^6 3s^1$

Vedclass · Answer

(C) The second ionization energy is the energy required to remove the second electron from a unipositive ion. For the configuration $1s^2 2s^2 2p^6 3s^1$,removing the first electron results in a stable noble gas configuration $(1s^2 2s^2 2p^6)$. Removing the second electron from this stable octet configuration requires a very high amount of energy. Therefore,the element with the configuration $1s^2 2s^2 2p^6 3s^1$ will have the highest second ionization energy.

Which of the following electronic configurations represents the highest second ionization energy for an element?
