This is a 10mm x 10mm x 10mm cube of almost pure (99.95% pure) Copper metal. It features laser etched symbol, name, atomic number and atomic weight in the front of the cube and density (in g/cm^3) and purity in the back.

Copper is a chemical element with the symbol Cu (from Latin: cuprum), atomic number 29 and atomic weight of 63.546. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys.

Great for chemistry and physics experiments or as a scientific desk toy.
