Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.
After that famous experiment, it was realized that atoms were mostly empty space.
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.

Ernest Rutherford published a paper proposing the planetary model in 1911. This followed the experiment performed by Hans Geiger and Ernest Marsden under the direction of Rutherford in 1909, where gold foil was bombarded with alpha particles .
he shot tiny alpha particles throug a piece of gold foil.
The conclusion was that an atom has a nucleus (center) with a positive charge.
The conclusion was that an atom has a nucleus (center) with a positive charge.
E. Rutherford discovered the proton.
He was an employed chemist and physicist.
Rutherford found that atoms have a nucleus

Ernest Rutherford's famous "gold foil" experiment changed the way we though of atomic structure. His demonstration proved that atoms have a small, dense nucleus which contains protons and neutrons. The electrons were shown to be outside the nucleus. Prior to this, we thought atoms had a consistent structure throughout, like soup or pudding.
i don 't know !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! nmdtmdt
Ernest and Mary gave birth to one daughter named Eileen Mary Rutherford
he found faults in the atomic theory of jj Thompson
