Javon Orr · Answer 1

C.

Explanation:

Quantum mechanics considers the electron as both a particle and a wave.

Because of its wave nature, the electron does not move in a fixed orbit. We can only say that we are more likely to find an electron in some areas of space rather than others.

Thus, the electron moves in a cloud-like region around the nucleus.

We cannot say that the electron stays in one position, moves randomly, or moves along an orbital path at a fixed distance from the nucleus.
