The behaviour of an electron in an atom is described mathematically by a wave function, or orbital. It turns out that each wave function contains three variables, called quantum numbers, which are represented as n, l and `m_1`. These quantum numbers describe the energy level of an orbital and define the shape and orientation of the region in space where the electron will be found.
