Answer:

They tell us where an electron is likely to be found.

Explanation:

To keep this quick and simple, I'll explain this briefly. For a clear and concise description, click here.

The quantum numbers are #n,l,m_l,#and #m_s#.

#n# is the energy level, and is also the electron shell, so the electrons will orbit there.

#l# is the angular momentum quantum number, which determines the orbital's (#s,p,d,f#) shape, and is also where an electron is likely to be found, with a probability up to #90%#.

#m_l# is the magnetic quantum number, and it determines the number of orbitals in a subshell.

#m_s# is the spin of an electron, and it is either up or down, with a spin of always #1/2#, and that means #m_s=+-1/2#.
