The ground-state electron configuration for copper (Cu) using noble-gas shorthand is [Ar] 3d¹⁰ 4s¹. This notation indicates that copper has a total of 29 electrons, with the argon (Ar) core accounting for the first 18 electrons, followed by a fully filled 3d subshell and one electron in the 4s subshell.
Neon (Ne) is a noblegas, as such it already has a filled electron shell (8 valence electrons) and don't form bonds to other atoms. So zero bonds, it is happy all by itself.
