Quantum Number

What does the Quantum Number tell us? What is it used for?

The quantum numbers tell us exactly where an electron is and its spin state in an atom.

The quantum number, or n, tells us which quantum level the electron is in and gives us restrictions for the other 3 quantum numbers.

a quantum number of n=1 tells us that the electron is in the 1st quantum level, and n=2 for the second quantum level, and etc.

In general, L must be one less than n, and the value of m must range in between -L and L. n, L, and m are quantum numbers that describe the state of an electron.

The principal quantum number (n) tells you which energy level (shell) the electron is in. The angular momentum quantum number (l) describes the shape/orbital (s,p,d,f). The magnetic quantum number (m) labels different orbitals of a subshell/orientation.
