Why are quantum numbers like an address?

Question

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

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#.

undefined Quantum numbers are like an address because they describe the specific properties and characteristics of an electron within an atom. Just as an address uniquely identifies a location, quantum numbers uniquely identify the location and energy state of an electron within an atom's electron cloud. Each quantum number (principal, azimuthal, magnetic, and spin) corresponds to a specific aspect of an electron's behavior and position within an atom, providing a kind of "address" for locating the electron within the atomic structure.
