The statement "atoms have a small, dense nucleus" is true. What evidence do scientists use to prove this statement as true?
Most alpha particles shot at gold foil go straight through, without any changes in their direction.


The particles ejected in Thomson's experiment bent away from the negatively charged plates, but toward positively charged plates.


A few alpha particles shot at gold foil bounce in the opposite direction


No matter which element Thomson put in a cathode ray tube, the same negative particles with the same properties (such as charge and mass) were ejected.
