What Is The Thinnest Thing On Earth?

The thinnest thing on earth is a single atom. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. However, we now know that atoms are made up of smaller particles: protons, neutrons, and electrons.
