Anode rays
Anode Rays:
An atom is electrically neutral but the formation of cathode rays has shown that all the atoms contain negatively charged electrons. So, atoms must also some positively charged particles to balance negative charge of electrons. This was the basis of discovery of protons. Before the identification of electron, E. Goldstein in 1886 discovered the presence of new radiations known as canal rays or anode rays. These are the positively charged rays which are seen moving from the anode towards cathode in a specially designed discharge tube (with a porous cathode), when a high voltage is applied across the electrodes. Porous cathode is used to provide the path for passing anode rays. It led to the discovery of another sub-atomic particle, the proton. Protons are positively charged particles and are denoted by ‘p+’
