Which conclusion could be made from ernest rutherford's gold foil experiment?
o atoms are made up of mostly empty space.
o atoms are mainly solid and block alpha particles.
o the volume of the nucleus is large compared to the rest of the atom.
o the mass of the nucleus is small compared to the rest of the atom.
