Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

This simulation explores the trends observed in orbital energies for the main group elements of atomic orbital energies.
