Question

rutherfords theory was identified by
using a beam of particles and detecting the scattering of the particles after they hit gold foil.
holding a magnet next to a beam of electrons and carefully analyzing the results.
using scanning tunneling micrograph images of atoms.
using only the experimental results of other scientists.

Explanation:

Rutherford's gold - foil experiment involved shooting a beam of alpha - particles at a thin gold foil and observing the scattering of the particles. This led to the discovery of the atomic nucleus. The other options do not describe Rutherford's experiment.

Answer:

using a beam of particles and detecting the scattering of the particles after they hit gold foil.
