This multi-day lesson plan helps students to understand how the models of the atom have changed and how quantum mechanics affects the electrons as they orbit the nucleus.

The website provides an explanation of the electrons' position in their orbitals as they spin around the nucleus. Quantum theory is also explored by explaining that the exact location of a specific electron is a not exact but a guess.
