The area of science that studies tiny particles like atoms is called physics, specifically the branch of atomic physics.

Here's why:

* Physics is the study of matter and its motion, as well as related concepts such as energy and force.

* Atomic physics focuses on the structure, properties, and behavior of atoms, which are the fundamental building blocks of all matter.

While other fields like chemistry also deal with atoms, their focus is more on how atoms interact with each other to form molecules and substances. Atomic physics dives deeper into the inner workings of the atom itself.
