
Used cathode ray tubes to cause elements to give off a stream of (-) charged particles Electrons
Figured out that (+) charged particles must be in atoms for there wasn’t an overall
charge
Proposed that Atom = (+) mass with (-) electrons inside. Uses raisin (-) bun (+) model
to prove so
Ernest Rutherford


Discovered that protons are in central nucleus
Does an experiment to prove so
Ernest Rutherford’s Experiment
First image shows what was supposed to happen according to the Raisin Bun model explain
and second image shows what actually happened
James Chadwick

Figured out about another sub atomic particle - Neutron - and added weight to the
atom with no charge at all
