Possible oxidation states are +4,6/-2. Electron Configuration. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. The correct electronic configuration of copper is [Ar] 3d10 4s1 Copper has atomic number 29 and due to the stability of half filled or fully filled orbitals or shells, the electrons from the 4s jumps to the 3d and makes the 3d shell contain 10 electrons.

Är det verkligen nödvändigt att överge en så underbar enkel bild av kärnans struktur Den elektroniska formeln för koppar är 1s2 2s2 2p6 3s2 3p6 3d10 4s1.

[Ar] 3d8 4s2. Copper [Ar] 3d10 4s1.

Chromium [Ar] 3d5 4s1 half-filled 3d orbital shell Copper [Ar] 3d10 4s1 filled 3d orbital shell WHY? Because we are being “naïve” by simply referring to the energy of orbitals! By saying“4s is lower than 3d”, we are neglecting the impact of e-e repulsion!

Cr: 4s23d4 → 4s13d5 and Cu : 4s2 3d9 → 4s1 3d10. s- electrons being less in number have little effect in this pursuit.

Ruthenium (Ru) electron configuration of copper [Ar] 3d10 4s1 and not [Ar] 3d9 4s2? In my text book it just says it is because it is more stable.

Well, because God wanted it that way. The [math]4s^{2}[/math] electrons, have SOME probability of occurring near the nuclear core, and while for the earlier transition metals, the NUCLEAR charge takes pre-eminence…the [math]3d^{10}[/math] subshell
