what does the electron cloud model describe?
Electron cloud is an informal term in physics. It is used to describe where electrons are when they go around the nucleus of an atom. The electron cloud model is different from the older Bohr atomic model by Niels Bohr. Bohr talked about electrons orbiting the nucleus, in a way similar to how the planets go around the Sun. The electron cloud model says that we can not know exactly where an electron is at any given time, but the electrons are more likely to be in specific areas.
