Dalton proposed it in Dalton's atomic theory (i think)
The atomic theory
John Dalton
The periodic table documents known elements, each of which are atoms. Different elements are defined by the number of protons in their nucleus. Atoms are the fundamental "building blocks" of chemical compounds. However, atoms are comprised of protons, neutrons and electrons. Hence, the "building blocks" of atoms are these three subatomic particles. Further still, protons and neutrons are comprised of even smaller particles called quarks. Hence, these are the "building blocks" of protons and neutrons. To summarise, elements are not the most fundamental particles which make up matter. They are however, for all intents and purposes, the fundamental particles in a chemical context.
No. The fundamental particles found in atoms are electrons, protons, and neutrons.
Atoms which can be further classified as protons, electrons and neutrons.

It was supposed that fundamental particles of atoms are proton neutron ( except hydrogen) and electrons but recent research confirmed that the basic constituents and fundamental particles of atoms or matter are six types of Quarks.
These particles are called atoms.

Yes, they are called atoms.
It's Atoms
Atoms, the fundamental chemical particles of matter, are very tiny, with dimensions of no more than a few nanometers and often only a few tenths of nanometers.
These particles are the atoms.
Particles that make all the matter is called an atom. Atoms are further divided as protons, neutrons and electrons. Recent studies have found that subatomic particles are made up of quarks. Atom is considered as an fundamental property of matter. Study of atoms tells us a lot about the characteristic of the element.
