What does the electron cloud model describe

Rapidly moving protons

Rapidly moving neutrons

Rapidly moving electrons

Rapidly moving nucleus

The electron cloud model describe s rapidly moving electrons.

We know they're in there somewhere, but we can't tell where. (That's NOT because they're too small. It's a fundamental rule of Physics that if we know something is moving fast, we can never measure its location accurately, no matter how good our measuring technology is.)
