प्रश्न
Why are anode rays also called as 'canal rays'?
उत्तर
When perforated rays were used in the discharge tube, another set of rays travelling in a direction opposite to that of the cathode rays, i.e. from the anode towards the cathode, is seen, as in the figure below. These rays are called canal rays because they passed through the holes or canals in the cathode. These rays were named positive rays or anode rays.

What is the significance of the number of protons found in the atoms of different elements?
Define: Electron
Define: Neutron
Explain in brief the experimental proof which led to the discovery of –
Protons
Is it possible for the atom of an element to have one electron, one proton and no neutron. If so, name the element.
Assertion: Proton can be defined as a hydrogen ion (H+).
Reason: These photons are produced when one electron is removed from one hydrogen atom.
