Answer:
A quantum number is a value that is used when describing the energy levels available to atoms and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrödinger wave equation for the hydrogen atom.
There are four quantum numbers:
》n - principal quantum number: describes the energy level.
》ℓ - azimuthal or angular momentum quantum number: describes the subshell.
》mℓ or m - magnetic quantum number: describes the orbital of the subshell.
》ms or s - spin quantum number: describes the spin.
Quantum Number Example
For the outer valence electrons of a carbon atom, the electrons are found in the 2p orbital. The four quantum numbers used to describe the electrons are n=2, ℓ=1, m=1, 0, or -1, and s=1/2 (the electrons have parallel spins).
Not Just for Electrons
While quantum numbers are commonly used to describe electrons, they may be used to describe the nucleons (protons and neutrons) of an atom or elementary particles.
