Discovered : known to ancient civilisations
Origin : The name is derived from 'Cuprum', the Latin name for Cyprus.
Description :A reddish-gold metal that is easily worked and drawn into wire. It has great ability to conduct both heat and electricity. Traditionally it has been one of the coinage metals along with silver and gold, but it is the most common and therefore the least valued of this group. Historically, copper was the first metal to be worked by people, and the discovery that it could be hardened with a little tin to form the alloy bronze gave its name to the Bronze Age. The metal is an essential element for humans.

- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
