-
Proposed that all mater is composed of vey small things (atom).
-
deflected cathode rays with an electrical field and the rays bent toward a positive pole, meaning the are negatively charged
-
Placed a sheet of gold foil infont of beam particles and shot the beam, once it hit the foil particles deflected of it. discovering every atom had a positively charged nucleus.
-
He suspended tiny droplets of oil in an electrical field and got an accurate measure of the charge
-
Illustrated how electrons can orbit around the nucleus, and move from higher to a lower orbit and energy was produced.
-
The electons were not located along circuits but just somewhere in a spherical zone. Because we cant know the exact location and velocity at the same time.
-
This addition complete the structure of the atomic model.
-
Electrons are embedded into a spherical positively charged cloud.
