How many m values are there for the 4f sublevel? In high school so no fancy words please!




With no fancy words:
The **orbital angular momentum quantum number** $ l $ is given by the letter you see there: **f**. Remember that we link this quantum number with integers in the following fashion:


1. $ l = 0 $: sublevel s.
2. $ l = 1 $: sublevel p.
3. $ l = 2 $: sublevel d.
4. $ l = 3 $: sublevel f. So we got it, $ l = 3 $.


How many orbitals we have? Well, we have $ 2l + 1 = 2\cdot 3+1 = 7 $. These seven orbitals are numbered from the value $ -l $ to $ l $, so you can list them in the following way:


$$ m = \{-3, -2, -1, 0, 1, 2 ,3 \} $$


Remember these $ m $ values are the **magnetic quantum numbers**. Sometimes you may find them with the symbol $ m\_l $.
