Question

In a discharge tube ionization of enclosed gas is produced due to collisions between

Easy

A

positive ions and neutral atoms/molecules
B

negative electrons and neutral atoms/molecules
C

photons and neutral atoms/molecules
D

neutral gas atoms/molecules

Solution

In a discharge tube, after being accelerated through a high potential difference the ions in the gas strike the cathode with huge kinetic energy.. This collision liberates electrons from the cathode. These free electrons can further liberate ions from gas molecules through collisions. The positive ions are attracted towards the cathode and negatively electrons move towards anode. Thus, ionization of gas results.
