Rutherford Model
RESULT
CONCLUSIONS
EXPLANATION
1. Most particles went straight through the foil.
Most of the atom is made up of empty space.
The particles were able to go through the foil because they hit empty space.
2. Some particles deflected back (bounced back).
The center of the atom is positive.
A positive charge repels another positive charge.
There are many Regents questions on this topic.
