| What do n, L, ML, and Ms mean? |
|
Definition
n = the principle quantam number and tells the size and amount of energy. [the higher the n the higher the energy].
L = tells the shape and type [ 0 is s, 1 is p, 2 is d, 3 is f]
ML = tells the number of positions and which orbital electrons are in.
Ms = tells the direction of the spin. [1/2 points up, -1/2 points down.] |
