Best Answer - Chosen by Voters

This saying is part of Dalton's Atomic Theory

His theory is composed of the following points:

1) All matter is made of atoms. Atoms are indivisible and indestructible. (he did not know of protons, neutrons, or electrons)

2) All atoms of a given element are identical in mass and properties (He did not know of Isotopes or Ions)

3) Compounds are formed by a combination of two or more different kinds of atoms.

4) A chemical reaction is a rearrangement of atoms. (But not a destruction of atoms)

5) The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative atomic weights.
