In Bohr's model of an atom, which of the following is an integral multiple of h/2π?

CONCEPT:

Bohr's Δtomic Model and Quantization of Δngular Momentum
\(L = n \frac{h}{2\pi} \), where n = 1, 2, 3,..

• According to Bohr's model, electrons revolve around the nucleus in specific allowed orbits without radiating energy.
• One key postulate of Bohr's model is that the angular momentum of an electron in these allowed orbits is quantized.
• This quantization means the angular momentum L is an integral multiple of the reduced Planck's constant \(\frac{h}{2\pi}\), i.e.,

EXPLANATION

• Potential energy, kinetic energy, and radius of the atom depend on the orbit number but are not themselves integral multiples of \(\frac{h}{2\pi}\) .
• The angular momentum being quantized as L = n frach2pi is a fundamental concept in Bohr’s theory, which explains discrete energy levels.

Therefore, the correct answer is Δngular momentum.
