The fundamental building block of all matter is **atoms**. Atoms are the smallest units of elements and make up all substances in the universe. Protons are subatomic particles found within atoms, while elements are pure substances made up of one type of atom, and compounds are substances formed from two or more different atoms chemically bonded together.
