Describe Thomson's Cathode Ray experiment and Rutherford's Gold Experiment, including the observed results that caused the scientific community to accept changes to Dalton's original model of the atom.

Cathode Ray experiment showed that all atoms contain tiny negatively charged subatomic particles or electrons.

Rutherford estimated the diameter of the nucleus, not the volume.

Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles.
