Leukippos and Democritus; possible also Mochus.
Democritus, in the 5th century, proposed his version of atomism. States that all matter was composed of small indivisible particles called atoms.
A solution is a homogeneous mixture whose particles are too small to reflect or scatter light. A colloid is a heterogeneous mixture containing particles that are small enough to stay suspended but large enough to scatter light.
The Greek philosopher Leucippus (5th century BC) and his pupil Democritus used the word "atom" to mean an indivisibly-small particle of matter. John Dalton (1766-1844) was among the first to use the concept to explain the observed chemical properties of compounds.
If I'm not mistaken, it was Montesquieu who argued that a republic could survive only in a small territory.
The very small size of virus particles was a major limiting factor of the discovery of viruses.
The particle theory of matter states that matter is made up of very small indivisible particles that are in constant motion.
Coining of the term "atom" and the idea that matter was composed of small, invisible, indivisible particles.
Around 400 BC Democritus a Greek philosopher theorized that everything was composed of small indivisible particles he called atoms or "atomos".
I'm sorry, I don't know what that means. Maybe this: Atomic theory is a theory that matter is made up of small particles called atoms

John dalton
monicales
They both proposed the theory that all matter consists of atoms.
The Greek philosophers Leucippus and Democritus first theorized about atoms. In fact, that's who named them atoms.
matter are composed by particles,particles are very small,particle have space between them
