ALL MOLECULAR GRAPHICS: metals: copper: atomic arrangement (crystal structure)
(above) copper #1 atoms arranged in a face centred cubic patternCopper: metal whose atoms are arranged in closely packed hexagonal layers. First and fourth layers are in line with each other. This gives what is known as a face centred cubic pattern or cubic close packing. Copper is is a very good conductor of electricity and is commonly used in electrical circuits. When alloyed (mixed) with tin it produces bronze.
