#1s^2 2s^2 2p^6 3s^1#

Explanation:

Since sodium is element number 11 on the periodic table, it implies a neutral stable #Na# atom has 11 electrons surrounding its nucleus in the ground state.

The electrons fill up according to the rules from the lowest energy level first, filling available s and p orbitals, with a maximum number of 2 electrons per orbital with opposite spins.
