Major contributions of:
Dalton. Allatter isadw up of atoms, which are particles too small to seeeacg element has its own kind of atom, with its own particular mass
Compounds are created when atoms if different elements link to form molecules.
Atoms cannot be created, destroyed, or subdivided in chemical changes.
Thomson. Atoms contain particles called electrons, which have a small Maas of a negative charge. The rest of the atom is a sphere of a positive charge
The electrons are embedded in the sphere so that the resulting atoms are neutral or unchanged
What are the three subatomic particles found in atoms?
