These experiments provided crucial evidence suggesting that atoms were not indivisible spheres but rather had internal structure, laying the foundation for further exploration into the nature of atomic particles and their properties.
The differences in conductivity among substances led scientists to hypothesize that atoms were composed of smaller particles with varying abilities to conduct electricity.
Conductivity experiments showed that some substances allowed the flow of electricity while others did not, indicating variations in atomic composition and structure.
Observations of how different materials interacted with static electricity suggested that atoms were not indivisible, as some substances conducted electricity while others did not.
