What are the four quantum numbers and give a brief description of what they indicate?
- 1) The principal quantum number (n) indicates size of the orbital. (1, 2, 3, etc.)
- 2) The angular quantum number (l) is related to the shape of the orbital. (from 0 to n-1)
- 3) The magnetic quantum number (ml) prescribes the orientation of the orbital. (-l through 0 to l)
- 4) The electron-spin quantum number (ms) describes the spin of the electron itself, not the orbital. (-1/2 or +1/2)
