jan 1, 1808 - John Dalton 1808
Dalton created an atomic model theory to explain why elements differ from each other. His theory stated that:
- Matter is made up of atoms.
- Each element has its own kind of atom, along with its own particular mass.
- Compounds are created when atoms of different elements are joined together.
- Atoms cannot be created, destroyed or subdivided in chemical changes.
He performed experiments and tested the results. Dalton performed experiments to test his theory.
