2. Forms of the same elements that differ isotopes
in amount of neutrons
3. When alpha particles were shot at a that the atoms of the metal were mostly empty
metal foil target, most passed through space, while the nucleus consisted of most of the
without deflections, while others de- mass which included highly condensed positive
flected at large angles. What did this particles (which caused the deflection).
