It showed that all atoms contain electrons.

Explanation:

The experiment carried out by J.J Thomson on the gas discharge tube by passing electric current through a tube filled with many different gases provided a good insight into the structure of an atom.

This experiment led to the development of the plum pudding model of the atom.

  • Cathode rays and it properties were discovered in this set up.
  • It furnished the scientific community with evidences that atoms can be divided into smaller parts.
  • Since atoms now contain some subatomic particles, they can be broken down in like manner into further bits.
  • The cathode rays which were later termed electrons became a fundamental particles known for every atom.
