In a discharge tube, at room pressure there is
Correct answer: C. No discharge
- A. Maximum discharge
- B. Minimum discharge
- C. No discharge
- D. Moderate discharge
Explanation
Discharge Tubes: Discharge tubes are used to study the behavior of gases under low pressure. They work by applying a high voltage across the tube, causing the gas to ionize and emit light.Room Pressure: At room pressure, the gas molecules are too close together. The collisions between gas molecules prevent the formation of a sustained electrical discharge.Low Pressure: In a discharge tube, the pressure is reduced to create a vacuum. This allows the electrons to travel longer distances without colliding with other molecules, leading to ionization and discharge.

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.
