* Neon's Electron Configuration: Neon has 10 electrons. Its electron configuration is 1s² 2s² 2p⁶. This means it has a full outer shell of electrons.

* The Octet Rule: Atoms tend to gain, lose, or share electrons to achieve a stable configuration with 8 electrons in their outermost shell (the octet rule). This is what makes noble gases like neon very unreactive.

Therefore, neutral atoms of neon have the same number of electrons as each of the following EXCEPT:

* Atoms with a different number of protons (atomic number). The number of protons defines the element. For example, an atom of sodium (atomic number 11) will have a different number of electrons than neon even if it gains or loses electrons to become an ion.
