Why was JJ Thomson's cathode ray experiment so important to modern atomic theory?

• he discovered protons, which meant there was something smaller than an atom

• he discovered the nucleus, which meant there was something smaller than an atom

• he discovered neutrons, which meant there was something smaller than an atom

• he discovered electrons, which meant there was something smaller than an atom

During Rutherford's gold foil experiment, some of the alpha particles bounced off at angles. What did this tell us about the atom?

• it is mostly empty space

• it has a positively charged nucleus

• it has electrons

• there are no subatomic particles
