What are the properties of anode rays? Why it is called canal rays? Who gave the name protons and why
Answers
Answer:
THE PROPERTIES OF ANODE RAYS ARE:
- THEY ARE MADE UP OF CHARGED PARTICLES i.e. posstive charge.
- THEY DEPEND UPON NATURE OF GAS TAKEN.
- ANODE RAYS ARE NOT PROTON. ANODE RAYS ARE MADE UP OF GASEOUS IONS.
- IN CASE OF HYDROGEN,ANODE RAYS ARE MADE UP OF PROTONS.
These rays are beams of particles moving in a direction opposite to the "cathode rays", which are streams of electrons which move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode.
Ernest Rutherford showed (1919) that nitrogen under alpha-particle bombardment ejects what appear to be hydrogen nuclei. By 1920 he had accepted the hydrogen nucleus as an elementary particle, naming it proton.

An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen Goldstein, in 1886.[1] Later work on anode rays by Wilhelm Wien and J. J. Thomson led to the development of mass spectrometry.
