1s^2 2s^2 2p^6
Neon is element number 10, so a neon atom has 10 electrons.
The n = 1 shell consists of one s orbital.
The remaining eight electrons fill the n = 2 shell. The n = 2 shell consists of an s subshell with a single s orbital and a p subshell with three p orbitals.
Each orbital can hold a maximum of two electrons.
Thus, there are two 1s electrons, two 2s electrons, and six 2p electrons.
Therefore, the orbital notation (or electron configuration) of neon is
1s^2 2s^2 2p^6.
