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.
Ernest Rutherford
The scientist that developed the iconic atom model that depicts a nucleus surrounded by electrons was Ernest Rutherford. Rutherford developed the model in 1911 after displaying some experiments that showed that the J.J.Thomson model was incorrect. Rutherford's experiment showed that an atom is a small but heavy central particle and is surrounded by a cloud of electrons. This was the opposite of what Thomson's model proposed.
we had a new model for the atom with a central nuecleus and orbiting electrons
He completely changed the model of the atom using his simple alpha scattering experiment.
E. Rutherford developed his atomic model due to the results of his gold foil experiment. His atomic model describes a small central, dense core and a surrounding volume of charged particles.
The modern atomic model is elaborated by Niels Bohr.
Ernest Rutherford created the nuclear model of an atom!
Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.

Ernest Rutherford was an investigator of atomic theory, and it was his model of the atom, the one with the mass concentrated in the center, that replaced the J.J. Thompson model. Links are provided below.
its was Ernest Rutherford who proposed the planetary atomic model

You think probable to Ernest Rutherford.

Ernest Rutherford. Added: I would think Neils Bohr here. Clarification: I think it was Rutherford. Bohr's work came after the "Rutherford Model". There are many places to read about this, eg Wikipedia " Rutherford Model". Certainly Bohr refined the Rutherford Model even before his quantum ideas for the hydrogen atom. That's why the "planetary model" is sometimes called the "Rutherford-Bohr Model."
