electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles‚ which he called an electron‚ was lighter than an atom of hydrogen by around 2‚000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.

Matter is made up and composed of atoms.These atoms have a core called nucleus.Atoms also have electrons orbiting around their nucleus.The core has positive charge while the electrons have negative charge.Rubbing causes unlike atoms to stick and unstick frequently. Atoms "fight" over electrons‚ and the stronger one gets to take the electron home.The triboelectric effect‚also known as triboelectric charging‚is a type of contact electrification on which certain materials become electrically charged
