J.J. Thomson identified the electron, a sub-atomic particle with a negative charge, thus demonstrating that atoms were not indivisible but composed of smaller, charged particles.
Through experiments involving the behavior of charged objects, scientists inferred that atoms must contain charged particles. This understanding was further solidified by the discovery of sub-atomic particles like electrons and protons.
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.
Experiments involving static electricity and conductivity of different substances provided early indications that atoms might have internal structure.
John Dalton proposed the idea of atoms being indivisible in the early 19th century as part of his atomic theory.
No, atoms are not indivisible. Sub-atomic particles, such as protons, neutrons, and electrons, exist within atoms, as discovered through experiments.
