The results of rutherford's gold foil experiment gave him the evidence to arrive at two conclusions: (1) an atom was much more than just empty space and scattered electrons and (2)

a) in any atom, electrons orbit a central nucleus.
b) all atoms were composed of three subatomic particles.
c) an atom must have a positively charged center that contains most of its mass.
d) an atom must have an equal number of positive and negative particles in a central location.
