When an electron remains between orbit, its momentum is _ ?

Explanation

Option A: This option suggests that the electron's momentum is not restricted to specific values and can take on any value continuously. However, in the context of electron orbitals in an atom, the momentum is indeed quantized and not dequantized. Option B: The momentum of an electron in an atom is quantized, which means it can only have specific values determined by the quantum mechanical properties of the atom. In the context of the electron orbiting the nucleus, the electron's momentum is restricted to discrete values. This is a consequence of the wavelike nature of electrons and the quantization of energy levels in atoms. Option C: This option is unrelated to the momentum of an electron between orbits. Emission typically refers to the release of energy or particles from an atom, such as when an excited electron transitions to a lower energy level and emits a photon. It does not directly address the momentum of an electron between orbits. Option D: This option suggests that the momentum of an electron between orbits constantly changes. While the momentum of an electron can change during transitions between energy levels or when interacting with other particles, within a specific orbit, the momentum remains constant due to its quantized nature.
