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

Options

  1. Aneutral gas atoms/molecules
  2. Bpositive ions and neutral atoms/ molecules
  3. Cnegative electrons and neutral atoms/ molecules
  4. Dphotons and neutral atoms/molecules

Correct answer

C. negative electrons and neutral atoms/ molecules

Step-by-step solution

Negative electrons and neutral atoms collides and causes the ionization of gas enclosed in a discharge tube.
