C)circumference of each orbit being an integral multiple of an electron wavelength.
D)none of the above

Question

Quizplus · Accepted Answer

The finding that electrons occupy discrete orbits in an atom was explained by the circumference of each orbit being an integral multiple of an electron wavelength, which is the basis of the concept of wave-particle duality and the quantization of energy. The other options are not directly related to this observation.
