1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil)
2) Atoms had a dense nucleus (because few alpha particles bounced straight back from the atoms)
3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
Rutherford proved that atoms: a. are mostly empty space; b. have a small, dense, positively charged nucleus; c. electrons are negatively charged, and far from the nucleus.
The Rutherford theory of the atom was correct; but after 100 years, of course, this theory was strongly developped, new experiments added and the today theory of the atom is more complex and detailed.
Rutherford found that there was a dense center to an atom.

It told them that the atom was mostly empty space.
Rutherford's experiment was important because it showed that an atom is mostly empty space. Rutherford gave more detail of the atom's structure.
Rutherford's major discovery of the structure of the atom occurred through his gold foil experiment. Check out the related link to learn more about this experiment.
The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.

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

Rutherford discovered that atoms are mostly empty space except for the nucleus at the center of the atom.
