Answer:

A total of four quantum numbers are used to describe completely the movement and trajectories of each electron within an atom. ... In other words, it refers to the size of the orbital and the energy level an electron is placed in.

Explanation:

To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms). The first quantum number describes the electron shell, or energy level, of an atom.
