What is the electron configuration for copper?

[Ar] 3d¹⁰ 4s¹Copper / Electron configuration

Does 3d or 4s fill first?

Thus the 4s subshell in the periodic table is filled before the 3d. In each element when we follow the occupation of electrons and the order in which the orbitals are filled, we see that the orbitals fill as following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d. Thus the 4s subshell in each element is filled before the 3d.

What is the electron configuration for zn2+?

The electron configuration of a neutral zinc atom is 1s22s22p63s23p63d104s2. The Zn2+ ion has lost two electrons, which leaves it with 30 protons and 28 electrons. The electron configuration of Zn2+ is 1s22s22p63s23p63d10.

What is electronic configuration of CR 24 and Cu 29?

Cu29 = 1s2 2s2 2p6 3s2 3p6 3d10 4s1 . Cr z=24 =1s2 2s2 2p6 3s2 3p6 3d5 4s1 .

What is the configuration of copper and chromium?

Electronic configuration of Chromium (Cu = 29) Cu (Z = 29) = 1s² 2s² 2p⁶ 3s² 4p⁶ 4s¹ 3d¹⁰Cu (Z = 29) = [Ar] 3d10 4s1These electronic configurations are unique since without filling the 4s orbitals completely, electrons entered into 3-d orbitals.

Is 4s closer to the nucleus than 3d?

In my textbook it is explained that 4s electrons show greater penetration than that of 3d electrons, and, thus, the energy of the 4s orbital is lower than that of the orbitals in a 3d energy sublevel. I took this to mean that 4s electrons are closer to the nucleus than that of 3d electrons.
