What shows up electrons?
Positive charge particles are called Protons Negatively charged particles are called Electrons Neutrons have no charge Protons was discovered by Ruther Ford Electrons was discovered by JJ Thompson Neutons was discovered by James Chadwick

What did JJ Thomson's cathode-ray tube experiment show?
Thompson observed that these rays are negatively electrically charged.
Who discovered the proton of an atom?
e. goldstein dicovered the proton. another kind of rays were found by him behind the cathode in the dicharge tube experiment similar to the one conducted by jj thompson.Goldstein was the first to record a ray of positively charge particles in a gas discharge. However, he did NOT find a consistent charge to mass ratio for the particles he was studying. This is no surprise, as some of these rays were protons and some where ionized nuclei. JJ Thompson DID find a consistent charge to mass ratio of his negatively charged particles in his cathode rays, and called these particles "corpuscles."Goldstein never made the intellectual leap of concluding that the positive particles in the rays he was studying were made of a single positive particle. It was Rutherford who first proposed, based on experimental results, that all elements were built out of the positive nuclei of hydrogen atoms.Goldstein
