Note that when writing the electron configuration for an atom like Cu, the 3d is usually written before the 4s. The electronic configuration of copper is [Ar]3d104s1. Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. Electronic Configuration [Ar] 3d 10 4s 1 is the electronic configuration of Copper. Cu has one more d electron and the same number of s electrons as Ni. The methods may be divided into two categories. Generally, copper is not a very reactive element and can be found existing in its free elemental form in nature. What is interesting about copper's electron configuration is that one electron is taken from the 4s shell and given to the 3d shell to complete it. Copper is found to a very minute extent in the animal body where it is said to catalyse the action of iron in the formation of haemoglobin.
