What did Ernest Rutherford's gold foil experiment demonstrate about atoms?

Answer:The answer is " Their positive charge is located in a small region that is called the nucleus"

Ernest Rutherford's gold foil experiment consisted in shooting positive particles called α particles, which are nuclei of helium atoms (2 protons and 2 neutrons), to a thin gold film.

Explanation:

Rutherford's Gold Foil Experiment proved the existance 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 matter.
