The Quantum Mechanical Model
Captions available
The idea
The quantum mechanical model describes an electron with a wavefunction, whose square gives the probability of finding it at a location.
In practice
Squaring hydrogen's ground-state wavefunction produces a probability cloud densest near the nucleus, thinning outward, rather than one fixed path.
Where people slip
A wavefunction gives probability, not certainty — it never predicts exactly where one electron will be found.
