Question

Why are quantum numbers like an address?

Answer 1

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`.
