Quantum Model

Problem solved

Bohr only worked for hydrogen…

The model

De Broglie: electrons as standing waves…

How it was discovered

Schrödinger's wave equation…

Practical application

Probability clouds, orbitals s/p/d/f…

Limitation

Exact solution only for hydrogen…

The principle: Δx · Δp ≥ ℏ/2…

Werner Heisenberg (1901–1976)…

The principle explains why we speak of an "electron cloud"…
