WebIn order to write the Copper electron configuration we first need to know the number of electrons for the Cu atom (there are 29 electrons). Once we have the configuration for Cu, the ions are simple. When we write the configuration we'll put all 29 electrons in orbitals around the nucleus of the Copper atom. WebCu(I) is an unstable state of copper. i Configuration 3 d 10 with no unpaired electrons makes Cu(I) diamagnetic. i Complete 3 d subshell precludes d-d state-to-state transitions, so Cu(I) is colorless like isoelectonic Zn(II). º Cu(I) compounds may be colored with certain anions CuI( s) — pale yellow Cu 2O( s) — brick red
