Question

Which of the following statements are true?

A. In Bohr’s initial work on the hydrogen atom, circular orbit is used to explain quantization of angular momentum

B. Photons have both wave and particle characteristics

C. EM radiation is a wave and cannot behave like a particle

In a hydrogen atom, the energy of an orbit can be split into different energies by an external magnetic field

Owing to the wave nature of electrons and the Heisenberg uncertainty principle, there are no well-defined orbits; rather, there are clouds of probability.

Explanation / Answer

TRUE :

Owing to the wave nature of electrons and the Heisenberg uncertainty principle, there are no well-defined orbits; rather, there are clouds of probability. :

Heisenberg Uncertainty Principle states that Position and Momentum of electron cannot be simultaneously measured with infinite prescision.
Therefore there is a cloud of probability where electron can be found and not a definite orbit of electron.
