Solid positive charge with negative electrons embedded in to it - by Thomson
What was the nuclear model?
Mass at the centre of atom and nucleus was charged - by Rutherford
What did Bohr discover?
That electrons orbit at specific distances
What did Chadwick discover?
Existence of neutrons in the nucleus
What did Rutherford experiement?
He fired alpha particles at gold foil, most went through but some bounced back. This showed that most of the mass was in the centre of the atom in a nucleus with a positive charge and that most of the atom is empty space.
