What is copper atom?

Copper is a chemical element with symbol Cu and atomic number 29. Classified as a transition metal, Copper is a solid at room temperature.

Are pennies made of copper?

The composition of pennies changed in late 1982, when zinc became the primary metal instead of copper. Before 1982, pennies were forged of 95 percent copper and 5 percent zinc. However, as copper became more expensive, it was abandoned as the primary metal. Pennies are now made of a zinc core and a thin copper coating.

What are the atoms in a penny made of?

The copper of a penny, for example, is made up of copper atoms. But sometimes atoms of different kinds join to make molecules. Copper atoms can combine with oxygen atoms from the air to make a molecule called copper oxide. The pennies looked dull and dirty because they were covered with copper oxide.
