Explain how electrons behave with regard to the electron cloud and how it is visualized.

Electrons behave very strange, they neither behave like a billiard balls nor like wave. Schrodinger's wave model tells that electrons exist in a distributed probability cloud. It has no defined position. There is always some uncertainity.

Electrons are in the electron cloud, which has a lot of space between it and the actual atom part. the electrons move insanely fast
