Question

based on the article \will the real atomic model please stand up?\ why did j.j. thomson experiment with cathode ray tubes? to specifically identify the nucleus as a separate part of an atom to determine that electric beams in cathode ray tubes were actually made of particles to prove john dalton and democritus wrong to determine the exact energy output of cathode ray tubes

Explanation:

J.J. Thomson experimented with cathode - ray tubes to show that the electric beams in them were made of particles, which he later identified as electrons. He was not focused on identifying the nucleus, proving Dalton and Democritus wrong in that context, or determining the energy output of cathode - ray tubes.

Answer:

to determine that electric beams in cathode ray tubes were actually made of particles
