WebNov 8, 2024 · Energy Levels When we describe the energy of a particle as quantized, we mean that only certain values of energy are allowed. Perhaps a particle can only have 1 Joule, 4 Joules, 9 Joules, or 16 Joules of energy. In this case, whenever we measure the particle’s energy, we will find one of those values.

WebAug 13, 2024 · You can see the symbol “2 - 2 + ” in this field. This means that the first electron has an m l value of 2 and and a spin of -1/2 and the second electron also has an m l value of 2 and an m s value of +1/2. The most populated field is the field for M L =0 and M s =0. There are overall five microstates with that combination of M L and M s values.
