- 3Alpha particle2 protons and 2 neutrons
- 4What were the results?Some atoms passed directly through,some bounced back
- 5What did the results meanThat atoms were mostly empty space but there was some area with a high concentration of positive charge.
- 6Rutherford's model proposed...-Atoms are made of two particles
-protons carry a positive charge
-electrons have very little mass
-electrons have a negative charge.
