Answer:

Electrons

Explanation:

Cathode ray tubes were used as the technology behind the discovery of electrons. At first, electrons were called cathode rays.

Using the discharge tube, scientists discovered electrons and they were shown to have the following properties:

  • they moved in a straight line and cast shadows of objects along their path
  • they attract positive charges and are repelled by the negative ones
  • they posses kinetic energy and can cause a mechanical paddle to move.

Electrons are therefore the particles produced in a cathode tube.
