COPPER

Copper was the first metal to be used by humans. It was probably used by "Neolithic man" to make tools as early as 7000 BC (9000 years ago). Copper weapons have been found dating from about 5000 BC. Because of its beautiful colour, copper was also used to make jewellery and ornaments.

SYMBOL AND ATOMIC #

Today, because it is such a good conductor of electricity, copper is mostly used in electrical generators and motors, for electrical wiring, and in electronic goods, such as radio and TV sets. Copper also conducts heat well, so it is used in motor vehicle radiators, air-conditioners and home heating systems.

Brass lock and key. Brass is an alloy of copper and zinc.
