Copper, its occurrence, and use. A. What is copper? Copper is a chemical element in the periodic table with the symbol Cu (from the Latin word cuprum, meaning ‘metal of Cyprus,’ where it was mined during the Roman era).Copper has an atomic number of 29 and atomic weight of grams per mole. It is an element in Group 11 of the periodic table, sharing many properties with silver and gold.

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 opaque, greenbanded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO (OH) 2. This experiment involves producing copper from copper(II) carbonate.
