How to write it
Place 10 electrons into subshells in the Aufbau order (1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p), filling s with 2, p with 6, d with 10 and f with 14. Neon sits in period 2, group 18, in the p-block, so its last electron enters a p subshell. Replacing the inner electrons with the previous noble gas gives the shorthand [He] 2s2 2p6.

Neon electron configuration FAQ
What is the electron configuration of neon?
1s² 2s² 2p⁶. Shorthand (noble gas) notation: [He] 2s² 2p⁶.
What is the noble gas configuration of neon?
[He] 2s² 2p⁶. The bracket stands for the He core electrons.
How many valence electrons does neon have?
8 (full outer shell).
How many unpaired electrons does neon have?
0 in the ground state, following Hund’s rule. With all electrons paired, the atom is diamagnetic.
