what did ernest rutherford use in his gold foil experiment?
alpha particles
beta particles
gamma radiation
ultraviolet radiation

Explanation:

Ernest Rutherford's gold foil experiment was a key experiment in nuclear physics. In this experiment, he used alpha particles. Alpha particles are positively charged particles (helium nuclei). He shot a beam of alpha particles at a thin gold foil. By observing how the alpha particles scattered, he was able to make important conclusions about the structure of the atom (such as the existence of a small, dense, positively - charged nucleus). Beta particles are electrons (negatively charged), gamma radiation is high - energy electromagnetic radiation (no charge), and ultraviolet radiation is also electromagnetic radiation (no charge). Since the scattering pattern in the gold foil experiment was based on the interaction of charged particles with the positive charge in the atom (nucleus), alpha particles (positively charged) were the appropriate choice.

Answer:

alpha particles
