How many unpaired electrons are there in Cu?

6

It is important to know that in chemistry, an unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair.  It is widely known the fact that Copper is a chemical element with the symbol Cu (cuprum in Latin) and atomic number 29.  It is interesting to know that Copper is 100% recyclable without any loss of quality whether in a raw state or contained in a manufactured product.  Cu has 6 unpaired electrons.
