In general, copper can donate either one or two electrons. The electronic configuration of copper is [Ar]3d104s1. Copper is the second example, after Chromium, of elements that don’t rigidly follow the simplest version of the rules for filling electron orbitals learned in introductory chemistry. Note that while filling electrons in various orbitals they are  filled according to the three laws – Aufbau, Pauli and Hund’s. 2. Thus, while the fllling of 3d-orbitals begins nickel (Ni), copper (Cu) and zinc (Zn). In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an electron from the 4s orbital is excited and rises to a 3d orbital. India is not rich in copper ores. Copper is an electropositive element, meaning it donates electrons to other atoms.

Romans and Greeks obtained this metal from the island of Cyprus from which the name ‘cuprum’ was derived.Occurrence: Copper constitutes only 0.0001 per cent of the earth’s crust. Combined state: The principal ores of copper are sulphides, oxides and basic carbonates. How to Find Electron Configuration. 1. Electron Configuration and Oxidation States of Copper. Electron affinity of Copper is 118.4 kJ/mol. Generally, copper is not a very reactive element and can be found existing in its free elemental form in nature. The electron configuration states where electrons are likely to be in an atom. The elements which show largest number of oxidation states occur in or near the middle of series (i.e., 4s 2 3d 3 to 4s 2 3d 7 configuration). Alternatively, write the symbol for the noble gas before an element (radon, in this case), and just add the extra information: Milk has a very low copper content. Home; Czech version; Table; Periodic table » Zinc » Electron configuration. This is expected that the configuration of copper is 3d94s2. The +2, or cupric, ion is more stable than the +1 cuprous ion. 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. Experimental evidence tells us that the electronic configuration of an atom of copper is actually: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 1 that is, the atom's ground state electronic configuration is more stable, of lower energy, if the 3d subshell is filled leaving the 4s subshell half-filled.
