What did eugen goldstein contribute in the history of atom?

Answer 1

He is sometimes called the discoverer of protons. He did experiments with cathode ray tubes, which knock electrons off atoms and attract them to a positively-charged electrode (the cathode). He noticed that a second stream of particles was attracted to the negatively-charged electrode (the anode), so he called them anode rays. However, it was left to one of his students to discover that these rays were sometimes pure protons. His experiments gave him a picture of atomic structure that was decades ahead of its time, and similar to what we know today. However, he did not follow up on his work, and was largely ignored by his peers.

Answer 2

He noted that cathode-ray tubes with a perforated cathode emit a glow from the end of the tube near the cathode. He concluded that in addition to the electrons, there is another ray that travels in the opposite direction, from the anode toward the cathode.

Answer 3

he discovered the proton using a cathode ray.

Answer 4

Eugene Goldstein discovered positive particles

Answer 6

Eugen Goldstein worked in the 19th century and is apparently credited with discovering the proton.

Answer 7

Eugene Goldstein discovered positive particles

Answer 8

Since he disvovered the cathode rays, the negative rays that were used in the Gold Foil experiment done by Thomson, he founded electrons.
