Answer #1

According to Bohr's model, the electron moves in circular orbits around a central nucleus and can only orbit stably in certain fixed circular orbits at a discrete set of distance from the nucleus.

But, we came to know that the energy of the electron in a given orbit is not fixed, thus the statemnet "an electron moves in a circular orbit around the nucleus" is not a valid statement stated.

Thus, option (C) "An electron moves in a circular orbit around the nucleus" is correct.

The Bohr Model of the hydrogen atom proposed that there were very specific energy states that the electron could be in. These states were called stationary orbits or stationary states. Higher energy states were further from the nucleus. These orbits were thought to be essentially spherical shells in which the electrons orbited at a fixed radius or distance from the nucleus. The smallest orbit is represented by n=1, the next smallest n=2, and so on, where n is a positive...
