Neon has zero unpaired electrons in its ground state. Here's why:

* Electron Configuration: Neon's electron configuration is 1s² 2s² 2p⁶.

* Filling Orbitals: This means all of neon's orbitals are completely filled. The 's' orbitals can hold a maximum of 2 electrons, and the 'p' orbitals can hold a maximum of 6 electrons.

* Unpaired Electrons: Unpaired electrons exist when an orbital has only one electron occupying it. Since all of neon's orbitals are filled, there are no unpaired electrons.
