Question

what did rutherford discover in the gold foil experiment? the presence of a large, dense, negatively charged solid surrounding the nucleus the presence of a small, dense, positively charged nucleus the presence of the electron the presence of the neutron

Explanation:

In Rutherford's gold - foil experiment, alpha particles were shot at a thin gold foil. Most particles passed through, but some were deflected at large angles. This led Rutherford to conclude that there was a small, dense, positively - charged nucleus in the atom. Electrons were discovered by J.J. Thomson, and neutrons by James Chadwick.

Answer:

The presence of a small, dense, positively charged nucleus
