Quantum_numbers_and_orbitals

In this tutorial, we will see how the quantum numbers predict the orbitals available in different energy levels.

Nuclear_physics

In this tutorial, we will learn about radioactive decay, nuclear stability, and what is happening on a subatomic level during a nuclear reaction.

Photons

Light can have wave-like or particle-like properties depending on the experiment being done. These "particles" of light are called photons. In this tutorial you'll learn about photon energy and momentum.

Atoms_and_electrons

Sometimes people draw atoms like little solar systems, but they're way stranger than that. In this section you'll learn how electrons can have wavelengths, jump orbitals, and emit photons while in an atom.
