A highly significant experiment improved scientists’ knowledge of how matter is arranged. During the experiment, particles were deflected after moving through a thin sheet of metal foil. Which particles were used, and what conclusion did the experiment lead to?
- Aalpha-particles; matter is made up of atoms
- Balpha-particles; atoms have a very small nucleus
- Cbeta-particles; matter is made up of atoms
- Dbeta-particles; atoms have a very small nucleus
