1s² 2s² 2p⁶

Here's a breakdown:

* 1s²: The first energy level (n=1) has two electrons in the 's' subshell.

* 2s²: The second energy level (n=2) has two electrons in the 's' subshell.

* 2p⁶: The second energy level (n=2) has six electrons in the 'p' subshell.

Neon is a noble gas, meaning it has a full outer shell of electrons, making it very stable and unreactive.
