Understanding Bohr's Model
Bohr's Model of the atom, proposed by Niels Bohr in 1913, revolutionized our understanding of atomic structure and electron behavior.
Key Features of Bohr's Model:
- Stable Orbits: Bohr suggested that electrons revolve around the nucleus in fixed orbits or energy levels. These orbits are quantized, meaning that electrons can only occupy specific energy levels without radiating energy.
- Energy Emission: Electrons can only gain or lose energy while transitioning between these orbits. When an electron jumps from a higher orbit to a lower one, it emits energy in the form of light or radiation. Conversely, it can absorb energy to jump to a higher orbit.
- No Energy Loss in Stable State: As long as electrons remain in the same energy level, there is no change in their energy. This explains why atoms are stable; the electrons do not spiral into the nucleus as they do not lose energy in stable orbits.
Comparison with Other Models:
- Rutherford Model: Proposed that electrons revolve around the nucleus like planets around the sun, but it could not explain the stability of atoms or the discrete energy levels.
- J.J. Thomson Model: Suggested a "plum pudding" model where electrons were scattered within a positively charged "soup." This model failed to account for the arrangement of energy levels.
Conclusion:
Bohr's Model is fundamental in explaining the stability of atoms and the behavior of electrons in quantized energy levels, making it the correct answer to the question regarding the energy of electrons in stable orbits.

Bohr’s model describes that there is no change in the energy of electrons as long as they keep revolving in the same energy level and atoms remain stable. This model was proposed by Niels Bohr in 1913. According to his model, electrons revolve in certain stable orbits around the nucleus without the emission of radiant energy. These orbits or shells are associated with definite energies and are also called energy levels. Hence, as long as an electron remains in the same energy level, its energy remains constant and the atom remains stable.
