- Alpha scattering experiment (Rutherford)
- Fired Alpha particles at thing gold foil
- Most went through- detected when they hit zinc sulfide screen
- Some alpha particles came straight back
- Most went through- detected when they hit zinc sulfide screen
- plum-pudding model results...
- 1) Some particles bounced back - small positively charged nuclei - repelled particles
- Rutherford's nuclear model of the atom says: -most of the mass must be concentrated at the centre, and most of an atom is empty space.
- Nucleus must be small and positive
- Faster travelling particle - less deflected.
- More positively charged nucleus - more particles deflected
- More close the particle passes to the nucleus - more it will be deflected
- More positively charged nucleus - more particles deflected
- Faster travelling particle - less deflected.

- Fired Alpha particles at thing gold foil
- removed air from the apparatus so: - Ionization doesn't occur and collision between alpha and air particles
