The idea of atoms explains the conservation of matter. In chemical reactions, the number of atoms stays the same no matter how they are arranged. So, their total mass stays the same.
According to Democritus' theory, atoms cannot be destroyed (an idea similar to the modern theory of the conservation of matter) and they exist in a vacuum or void, which corresponds to the space between atoms. Atoms of a liquid are smooth and round; atoms of a solid are jagged and catch on to each other. Atoms differ only in shape, position, and arrangement.
Lamarck
this phrase refers to the" law of conservation of mass ".this law states that the total mass of the reactants is equal to the total mass of products after reaction has completed .or the total number of atoms taking part in a chemical reaction as reactants is equal to the total number of atoms obtained as products
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.
the Greeks. Atoms were thought to be the last indivisible units, but we've learnt how to split atoms.

atoms
It was not John Dalton who first suggested the idea of atoms. It was the Greek philosopher and mathematician Democritus who first suggested the existence of atoms.
The concept of atoms as fundamental building blocks of matter dates back to ancient Greece, but gained acceptance in the early 19th century. Atoms are composed of subatomic particles including protons, neutrons, and electrons. Modern physics has since revealed a more complex subatomic structure within atoms.

School dates back as far as the Greek times. But the people who established the school system were called the Byzantines.
All atoms of one type were identical in mass and properties. (Apex 2021)
