John Dalton..
Discovered that the atom was mostly empty space with a small dense and positively charged nucleus ( Gold Foil Experiment)
discovered subatomic particles ( Cathode Ray Experiment, Plum Pudding Model)
Atoms cannot be created or destroyed, atoms combine in whole # ratios ( Billard Ball Model)
Discovered that electrons can be found in specific paths called orbits, hydrogen gas emits certain frequencies ( Bohr model)

discovered the neutron
the electron behaves like a wave, electron position is a probability ( electron cloud)
Atoms cannot be created or destroyed, atoms combine in whole # ratios ( Billard Ball Model)
