According to Bohr's atomic model, the emission or absorption of energy by electrons occurs
Correct answer: C. when electrons change their orbits.
- A. randomly.
- B. continuously.
- C. when electrons change their orbits.
- D. when electrons become positively charged particle.
Explanation
* Bohr's model postulates that electrons exist in specific, fixed energy levels or orbits around the nucleus. They do not emit or absorb energy while residing in these stable orbits. Energy is only emitted when an electron jumps from a higher energy orbit to a lower one, and energy is absorbed when an electron moves from a lower energy orbit to a higher one. This energy change is in the form of discrete packets called photons.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
