Atomic orbitals are typically categorized by n, l, and m quantum numbers, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively.

Atomic orbitals are the basic building blocks of the atomic orbital model ( alternatively known as the electron cloud or wave mechanics model ), a modern framework for visualizing the microscopic behavior of electrons in matter.

Atomic orbitals may be defined more precisely in formal quantum mechanical language.

Atomic orbitals can be the hydrogen-like " orbitals " which are exact solutions to the Schrödinger equation for a hydrogen-like " atom " ( i. e., an atom with one electron ).
