How did Rutherford discover the proton?

• Cathode tube ray experiment
• Gold Foil Experiment
• Planetary Model
• Plum Pudding Model

Who stated that all atoms of the same element are excacty alike?

• Democritus
• Dalton
• Thomson
• Borh

What scientist is best known for his "Plum Pudding" model of the atom?

• J.J. Tomson
• Ernest Rutherford
• John Dalton
• Democritus

J.J. Thomson provided evidence that an atom...

• is the smallest particle of matter
• contains negatively charged particles
• has an overall negative charge
• has an overall positive charge

Rutherford's gold foil experiment provided evidence that...

• negative and positive charges are spread evenly throughout the atom.
• alpha particles have a positive charge.
• gold is not a dense as previously thought.
• there is a dense positively charged nucleus at the center of an atom.
