Did Ernest Rutherford create the mini solar system model an atom?
Yup, by doing the “Gold Foil Experiment” he found that most particles went straight through a sheet of gold foil, while only a very tiny percent was deflected. This meant that the atom was mostly space, it had a tiny solid core called a nucleus, the nucleus is positivley charged and he beleived that the electrons surrounded the nucleus like how planets orbit the sun.
