The electronic configuration of the atom that represents excited state is P:

Explanation:

There are 2 states classified under energy levels:

For the given options:

The atomic number of sodium element is 11. The ground state electronic configuration of this element is

The atomic number of neon element is 10. The ground state electronic configuration of this element is

The atomic number of nitrogen element is 7. The ground state electronic configuration of this element is

The atomic number of phosphorus element is 15. The ground state electronic configuration of this element is

One electron from the valence shell jumps into outer shell and the excited state electronic configuration becomes

The atomic number of helium element is 2. The ground state electronic configuration of this element is
