A discharge tube containing `H_(2)` gas at low pressure is subjected to high voltage. Will there be emission of protons from the anode?

Text Solution

Verified by Experts

In a discharge tube, anode rays are not emitted from the anode. Therefore protons are not emitted from the anode. However, they are produced from `H_(2)` gas, by the knockout of the electrons by high speed cathode rays.
