An atom is the smallest piece of matter that has the characteristic properties of a chemical element, such as hydrogen, oxygen, calcium, iron, gold, and neon. More than 90 types of atom exist in nature, and each one forms a different element. Elements are made up of only one type of atom—gold contains only gold atoms, and neon contains only.

The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles.
