5 Multiple choice questions

  1. from his gold foil expirments, he knew some substances give off + charged particles called alpha particles, most of the mass of an atom is in the nucleus, he reasoned that electrons in the atom are whirled around outside the nucleus, most of the atom is empty space
  2. a mass of an atom expressed in relation to the defined standard of 12 amu (1 carbon atom)
  3. a powerful force of attraction that binds protons and neutrons together in the nuleus
  4. Conducted by Ernest Rutherford in which alpha particles that were shot at gold foil were deflected when they hit the positive center of gold atoms. The nucleus was discovered as a result of this experiment.
