Vedclass · Answer

(C) The total number of electrons in the given configuration is $2+2+5+1 = 10$. An element with $10$ electrons in its neutral state is Neon $(Ne)$. The ground state electronic configuration of Neon is $1s^2 2s^2 2p^6$. In the configuration $1s^2 2s^2 2p^5 3s^1$,one electron from the $2p$ orbital has been promoted to the $3s$ orbital. Therefore,this represents the excited state of the Neon atom.
