Copper has an atomic number of twenty-nine and an atomic weight of sixty-three point five-hundred and forty-six. The symbol for copper is Cu. Most people think that the penny is primarily made of copper, but actually only the outer coat is made of copper. The inside is made of zinc. It used to be made of all copper, until 1981. However, The Statue of Liberty is made mostly of copper; it doesn’t show though because it is green. After years and years the copper began to rot and now only the top of the torch on the statue isn’t rotten. Copper is said to be one of the most familiar metals of everyday life. Long ago copper was used for many things, like buttons on a policeman’s coat. Copper is used in the alloy brass, with zinc. Copper is found in many American bathrooms. It is used in the many pipes that are found in bathrooms. Copper is the best conductor of electricity out of the elements. The name for copper comes from the Latin word cuprum which means “From Cyprus.” Cyprus is an island that the Romans found copper on. It isn’t really known who discovered copper, because they’ve found copper jewelry in Iraq, which dates back to 9000 B.C. Copper is actually a quite rare element, it actually only makes up seven thousandths of the Earth’s crust. That’s not even one whole number! When ever copper combines with other elements to make an alloy, it usually ends up creating a tougher metal than any other element that it was combined with, like brass for example. Copper has a pretty brownish reddish color that makes it famous.
