It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a reddish-orange color.The filled d-shells in these elements contribute little to interatomic interactions, which are dominated by the s-electrons through metallic bonds.Unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak.

This is because the resistivity to electron transport in metals at room temperature originates primarily from scattering of electrons on thermal vibrations of the lattice, which are relatively weak in a soft metal.

In humans, copper is found mainly in the liver, muscle, and bone.
