Isotopes of the Carbon atoms are 12C 6, 13C 6, 14C 6. Goldstein studied at the University of Breslau (now in Wrocaw, Pol.), where he received his doctorate in 1881. Isotopes of the Hydrogen atoms are Protium ( 1H 1), Deuterium ( 2H 1) and Tritium( 3H 1). 25, 1930, Berlin), German physicist known for his work on electrical phenomena in gases and on cathode rays he is also credited with discovering canal rays. The base structure of the Crookes tube consists of an empty tube made of glass, inside which gases circulate. He then made modifications to the structure developed by William Crookes in the 19th century. Isotopes are the elements that have the same atomic number but different mass. Experiments with cathode rays Crookes tubes Goldstein began his experiments with Crookes tubes during the decade of the 70s. These neutrally charged particles are termed Neutrons. Neutrons: A subatomic particle with no charge and a mass equivalent to protons in the nucleus of all atoms were discovered by J.Protons: In 1886, Ernest Goldstein discovered that anode emitted positively charged particles with a different condition in the same tube, known as Canal rays or as Protons.Then these negatively charged particles are proposed as Electrons. Thomson discovered negatively charged particles towards the anode, these rays are emitted by the cathode in a cathode ray experiment.
