is excited oxidation state

Answer 2

this occurs due to the absorption of the energy which is provided when the atom of neon moves from the relaxed state to the excited state.

Explanation:

• When neon is provided with a particular amount of energy it is converted into the excited state. During the excited state there is jump of the electron from the s- orbital to the 3rd  p- orbital.

• This result of this is that the p- orbital is not completely filled and also there is electron in the s-orbital during excited state but in relaxed state electron from the 3S orbital and jump back into the 2P orbital
