What did rutherfords gold foil experiment him conclude

the existence of the nucleus of an atom

Explanation:

Rutherford's Gold Foil Experiment proved the existence of a small massive center to atoms, which would later be known as the nucleus of an atom. Ernest Rutherford, Hans Geiger, and Ernest Marsden carried out their Gold Foil Experiment to observe the effect of alpha particles on the matter.

Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
