Quantum Numbers

principal quantum number

symbolized by n, indicates the main energy level occupied by the electron

angular momentum quantum number

symbolized by l, indicates the shape of the orbital

magnetic quantum number

symbolized by m, indicates the orientation of an orbital around the nucleus

spin quantum number

symbolized by s, the quantum number that has only two possible values, +1/2 and -1/2, which indicate the two fundamental spin states of an electron in an orbital
