Ernest Rutherford devised an experiment in 1911 to probe the structure of the atom. Observations and Possible Conclusions from the Rutherford Gold Foil Experiment 1. The reflected alpha particles bounced off of the positively charged nucleus - which proved the existence of the nucleus 2. The reflected alpha particles bounced off the atoms in the gold foil - which proved the existence of atoms 3. Most of the alpha particles went straight through the gold foil undeflected - which proved that atoms are neutral 4. Most of the alpha particles went straight through the gold foil undeflected - which proved that the positive charge was spread evenly through the atom Which of these conclusions did Rutherford draw?
