Properties
Copper (Cu) is a reddish metal with an atomic number 29, standard atomic weight of 63.546, and melting point of 1357.8 K at 1 atm. It was moderately volatile during the Earth formation by accretion of solid material condensed from the solar nebula. As a siderophile element, it partitioned into the core during the separation of metallic core from molten silicate...
