John Dalton
The postulates of this theory may be stated as follows:
- Matters are composed of very tiny particles called atoms.
- These particles are too small to see and cannot be created or destroyed in a chemical reaction.
- Atoms of a specified element are identical in mass and chemical properties.
- Atoms of different elements have different masses and chemical properties.
- Atoms combine in the ratio of small whole numbers to form compounds.
- The relative number and kinds of atoms are constant in a given compound.
