Question

when an electron remains between an orbit it's momentum will​

Answer 1

Answer:

The first postulate of Bhor theory is that the orbital momentum of the electron is quantized ie, L = mvr = nh where h is Drac constant.

Answer 2

When an electron remains between an orbit it's momentum will quantized.​

Explanation:

• Quantization of orbital energy is caused by the wave nature of matter. Allowed orbits in atoms occur for constructive interference of electrons in the orbit, requiring an integral number of wavelengths to fit in an orbit’s circumference.
• Owing to the wave nature of electrons and the Heisenberg uncertainty principle, there are no well-defined orbits; rather, there are clouds of probability.
• Bohr correctly proposed that the energy and radii of the orbits of electrons in atoms are quantized, with energy for transitions between orbits given by ΔE = hf = Ei − Ef, where ΔE is the change in energy between the initial and final orbits and hf is the energy of an absorbed or emitted photon.
• The allowed orbits are circular, Bohr proposed, and must have quantized orbital angular momentum given by

     L = $m_{2}vr_{4}$ = n $\frac{h}{2\pi }$ (n = 1,2,3,)

where L is the angular momentum, $r_{n}$ is the radius of orbit n, and h is Planck’s constant.
