Which statement is true about the electrons in the Bohr model of an atom?

• A. Electrons can exist anywhere around the nucleus without restriction.
• B. Electrons lose energy continuously as they orbit the nucleus.
• C. Electrons are located only in the nucleus.
• D. Electrons occupy fixed energy levels and move in circular orbits around the nucleus.

Answer: (D)

Verified step by step guidance

1. Recall that the Bohr model of the atom describes electrons as moving in specific, fixed circular orbits around the nucleus, each corresponding to a quantized energy level.
2. Understand that in this model, electrons cannot exist just anywhere around the nucleus; they are restricted to these discrete orbits with defined energies.
3. Recognize that electrons do not lose energy continuously while orbiting; instead, they remain in a stable orbit unless they absorb or emit a photon to jump between energy levels.
4. Note that electrons are not located in the nucleus; the nucleus contains protons and neutrons, while electrons orbit around it.
5. Therefore, the true statement is that electrons occupy fixed energy levels and move in circular orbits around the nucleus, as described by the Bohr model.
