magnetic quantum number ml
The magnetic quantum number (ml) for any give orbital lies between -i to +l; here, l is the orbital quantum number. The magnetic quantum number basically signifies the spin of the electrons in the shell which in a way denotes the different energy levels.The quantum number m refers, loosely, to the direction of the angular momentum vector. The magnetic quantum number m only affects the electron's energy if it is in a magnetic field This means that each electron with a different ml will have a different energy level.The magnetic quantum number associated with the quantum state is designated as m.
