It is impossible to know the precise location of an electron around the nucleus of an atom at any given time, so it must be described as the total probability of finding an electron within a region of space. With the Quantum Leap Lab: Probability and Electron Structure—ChemTopic™ Lab Activity, investigate by analogy the relationship between probability and the electronic structure of an atom by dropping a marble repeatedly onto a target from two distances.
