For example, sodium (atomic number 11) has its 11 electrons distributed in the first three shells as follows: the K and L shells are completely filled, with 2 and 8 electrons respectively, while the M shell is only partially filled with one electron.
The electron configuration of sodium is 1s^2 2s^2 2p^6 3s^1. This means that sodium has 11 electrons distributed in its energy levels, with 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, 6 electrons in the 2p orbitals, and 1 electron in the 3s orbital.
