we had a new model for the atom with a central nuecleus and orbiting electrons
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.
In Rutherford's gold foil experiment atoms are mostly empty space.

Ernest Rutherford concluded that an atom contains a very small, dense center, called a nucleus, with a positive charge as a result of his gold foil experiment.
After that famous experiment, it was realized that atoms were mostly empty space.
Ernest Rutherford was responsible for the Gold Foil experiment. A great portion of Ernest Rutherford's research included the study of alpha particles.

The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
Ernest Rutherford suggested that most of the mass of the atom is located in the nucleus. He came to this conclusion after finding the results on his famous gold foil experiment. This is where he fired radio active particles through very thin metal foils, and detected them using screens covered in zinc sulphide.
The gold-foil experiment
Anybody who knows much about atoms and is willing to ignore virtual particles. The credit for actually discovering this should probably go to Rutherford. (Or Rutherford, Geiger, and Marsden ... Geiger and Marsden actually did the experiment in Rutherford's lab, and Rutherford was the one who explained the results.)

Rutherford used the gold foil experiment to figure out that an atom had charged particles in the nucleus
