Electron Configuration Of Copper Ii. The electron configuration of copper is: In general, copper can donate either one or two electrons.
1s2 2s2 2p6 3s2 3p6 3d10 4s1. 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10. Electron configuration indicates how many electrons an atom or ion has, and how they are distributed on electron orbitals.
Electron configurations of copper (i) and copper (ii) post by chem_mod » wed oct 21, 2015 6:16 pm the roman numerals refer to the oxidation state of an atom.
Write the complete electron configuration for the copper(i)ion. Copper (cu) has two valences cu i (cuprous) has one valence electron and cu ii (cupric) has two valence electrons. Cu(i) is an unstable state of copper. Although this is apparently contradictory to the usual rule, cu 2+ really is more stable than cu 1+.
