EOY Chemistry Review

Einstein came up with the plum pudding model of the atom showing that atoms were

not solid.

J.J. Thomson discovered the electron by observing a beam of them in a cathode ray tube.

Bohr came up with the planetary model showing that electrons move in circles around

the nucleus.

Schrodinger created the electron cloud model that shows that electrons move in waves within

a cloud of space

The Heisenberg uncertainty principle demonstrates that it is impossible to

determine accurately both the location and velocity of an atomic particle.

Rutherford's gold foil experiment demonstrated that most of the mass of an atom

is in a tiny center called the nucleus.

Thompson Discovers The Electron by Performing a Cathode Ray Tube Experiment

Bohr argued that positive and negative charge are evenly scattered about in the atom, and created the plum pudding model of the atom.
