He said that matter was made of small, hard particles that he called “atoms”.

All substances are made of atoms. Atoms are small particles that cannot be created, divided, or destroyed. Atoms are invisible.
Atoms join together to make new substances (molecules).

He discovered the protons and nucleus.
