Pressure in the gas discharge tube was kept to produce cathode rays
Correct answer: D. 0.01 torr
- A. 10 torr
- B. 1 torr
- C. 0.1 torr
- D. 0.01 torr
Explanation
0.01 torr) - Correct: Best pressure for cathode ray formation. For the production of cathode rays, the gas pressure in the discharge tube must be very low.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
