Copper is a Transition Metal in group 11. It has a Orthorhombic crystalline structure.
This element has two stable isotopes: 63 and 65.
Copper seems to be rare on the Moon. As it is one of the main industrial metal, it will either be imported or replaced by aluminum. Replacement of copper by aluminum on Earth has been accomplished in a number of fields, but a lot of work would be required to replace all uses of copper.
Copper is an essential trace element in food. A typical human body contains 0,000072 kg[1]. For one million persons the copper required would be 72 kg. For an entire ecosystem serving these one million people the amount required might be less a few tonnes (hypothetical ratio of 100:1).
