### The values of L and ML

In the lecture, we went over that l=n-1 but it also says that it can be anything lower than n. Why is this, and when do we stick to n-1?

l refers to the subshells of n. The allowed values of l depend on the value of n and range from 0 to n-1. For example, if n=3, then l can = 0, 1, or 2.

L just refers to what sub shell the electron is in. The point of L=n-1 is to show the max value of L that it could be. So the value of L is not always going to be n-1.

### Re: The values of L and ML

l = n-1 refers to the max value of l. This means that the value of l can be lower than n-1, but not higher. For example, the 3p orbital is n=3 and l=1. The l value can either be 0, 1, or 2. Since n=3, l max is l=3-1=2, so for n=3,the possible orbitals are 3s, 3p, 3d.
