The atom.
The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
The discovery of the atomic nucleus was made during the gold foil experiment by Ernest Rutherford in 1909. He observed that most of the alpha particles passed straight through the gold foil, indicating that atoms have a small, dense nucleus at their center.
Rutherford supervised the experiment in his famous beta particle scatter experiment with gold foil, so he is given credit.

Ernest Rutherford conducted the gold foil experiment in 1909 at the University of Manchester. He aimed to investigate the structure of the atom and discovered that atoms have a small, positively charged nucleus at their center.
The smallest particle of matter is an atom, which was discovered in the early 20th century through experiments such as the gold foil experiment by Ernest Rutherford. It was found that atoms are made up of even smaller particles called protons, neutrons, and electrons.
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.

Ernest Rutherford is the scientist who conducted the gold foil experiment in 1911 and discovered that atoms have a small, dense nucleus at their center. This experiment led to the isolation and identification of the atomic nucleus.
The gold foil experiment supplanted the plum pudding theory. The gold foil experiment led to the discovery that most of the atoms mass is located in the dense nucleus.
