The quantum numbers of most energetic electron in Ne atom when it is in first excited state is:

View answer and explanation

Correct option: C

3,\;0,\;0,\; + 1/2

Option C (

3,\;0,\;0,\; + 1/2

) is correct because the electronic configuration of the first excited state of Ne is

1s^22s^22p^53s^1

, and the most energetic electron is in the 3s orbital.
