I'm not sure, but it is definitely a scientist from this list: Democritus, Thomson, Bohr, Rutherford, Dalton, or Schordinger and Heisenberg.

All substances are made up of tiny particles called atoms.
All substances are made of atoms, except the substance that makes up a neutron star.
All substances are made up of atoms, living or nonliving. Atoms do have subatomic particles though.
Atoms! All matter is composed of atoms. Whether it's a pure sample of an element, a compound, or a mixture; solid, liquid, or gas, it all comes down to atoms. The word atom was coined by a Greek thinker named Democritus, who was the first to theorize that all matter was made up of some kind of indivisible particle, which he called "atomos," meaning indivisible. Thanks, Democritus!
John Dalton believed that all elements are made of atoms and that atoms are identical if they are of the same element. He is the first one to have combined substances to make new substances through chemical reactions.
No. Substances are made of atoms. Some atoms combine with other atoms to form compounds.
