For the study of particles, discharge tube is filled with:
Correct answer: D. All of these.
- A. Gas.
- B. Air.
- C. Vapours of a substance.
- D. All of these.
Explanation
The discharge tube can be filled with air. It can also be filled with the vapor of a substance, such as mercury vapor, in addition to gas at low pressure. When an electric current is passed through the tube, the gas inside the tube ionizes and emits light. This light is used to study the properties of particles.

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.
