From his experiments ,j. j thomson concludes what?

Thomson made the following conclusions: The cathode ray is composed of negatively-charged particles. The particles must exist as part of the atom, since the mass of each particle is only ∼ 20001start fraction, 1, divided by, 2000, end fraction the mass of a hydrogen atom.

Explanation:

J J Thomson's experiment confirms the existence of corpuscles (electrons), by concluding that: cathode rays are charges of negative electricity carried by particles of matter.

Explanation:

J J Thomson's experiment with cathode ray tubes helped him to discover the electron (which Dalton did not know about).

Cathode ray is composed of negatively-charged particles. And these particles must exist as part of the atom, since the mass of each particle is only ∼ 20001start fraction, 1, divided by, 2000, end fraction the mass of a hydrogen atom. And also, that the particles that made up the gases were universal.
