Cathode rays travel in discharge tube from:
Correct answer: B. Cathode to anode
- A. Anode to cathode
- B. Cathode to anode
- C. Glass tube to vacuum pump
- D. Cathode through air
Explanation
Cathode rays come from the cathode because the cathode is charged negatively. So, those rays strike and ionize the gas sample inside the container. Therefore, cathode rays travel in discharge tube from cathode to anode.

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.
