According to Bohr's model of the atom, which statement is correct?

• A. Electrons lose energy continuously as they orbit the nucleus.
• B. Electrons can exist anywhere around the nucleus without restriction.
• C. The energy of an electron depends only on its distance from other electrons.
• D. Electrons orbit the nucleus in fixed energy levels without radiating energy.

Answer: (D)

Verified step by step guidance

1. Recall the key postulates of Bohr's model of the atom, which was developed to explain the stability of atoms and the discrete spectral lines observed in hydrogen.
2. Understand that according to Bohr, electrons move in specific circular orbits around the nucleus, each orbit corresponding to a fixed energy level.
3. Recognize that electrons in these fixed orbits do not emit energy continuously; instead, they only emit or absorb energy when they jump between these energy levels.
4. Note that this model contradicts the classical idea that electrons lose energy continuously and spiral into the nucleus, which Bohr's model successfully avoids.
5. Therefore, the correct statement is that electrons orbit the nucleus in fixed energy levels without radiating energy, which explains atomic stability and discrete spectral lines.
