Question

Quantum model of an atom

Answer 1

Answer:

They called this theory quantum theory, or quantum mechanics. Quantum theory describes matter as acting both as a particle and as a wave.As we have discussed, electrons in atoms behave like waves. They exist as a fuzzy cloud of negative charge around the nucleus, instead of as a particle located at a single point.

Answer 2

Answer:

Erwin Schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves. ... An atomic orbital is defined as the region within an atom that encloses where the electron is likely to be 90% of the time.
