### How to Find the Number of Orbitals

We haven't mentioned in Lecture 1 yet, but how do you find the number orbital of in a sub shell??

### Re: How to Find the Number of Orbitals

You can find the number of orbitals in a subshell based on the angular momentum number (l). The possible orbitals (ml) can have values {-l,...,+l}. So if l = 1, then the ml can have values {-1,0,1}. There are 3 values in this set, so the subshell can have three orbitals.

Start with identifying the principle quantum number (n) to determine the shell
Next identify the shape using the allowed values: l= 0,1,2,..., n-1
Use the l you calculated to find the different orbitals of a subshell (ml)
ml has the allowed values: ml= l, l-1, ..., -l

### Re: How to Find the Number of Orbitals

the letter ml is used to denote the amount of subshells in an orbital. Typically, the amount of subshells in an orbital is from l,l-1..0..-l.
