Terminology with quantum numbers

While I was doing the homework problems, I came across some questions where I wasn't sure which quantum number they were asking me to find. So I just wanted to make sure:

- when they ask for the number of orbitals, does that mean the quantum number ml?
- when they ask for the number of subshells, does that mean the quantum number l?
- when they refer to a shell, does that mean the quantum number n?
- and would ms just be the spin?

Sorry for the many questions!

Thank you!!

Hi Anna,
- When they ask for the number of orbitals, does that mean the quantum number ml
- The quantum number ml refers to the magnetic quantum number. This number is in charge of determining the number of orbitals, and what their rotation is in the sub shell. It can be negative, zero, or positive.

- When they ask for the number of subshells, does that mean the quantum number l?
- The quantum number l refers to the orbital angular momentum quantum number. This determines the shape of an orbital. Each l value is in charge of indicating the specific s,p,d,and f sub shell. Values can be zero or positive.

- When they refer to a shell, does that mean the quantum number n?
- N is the principal quantum number, it describes the distance of the electron away from the nucleus. It can be any number that is positive, starting from 1.

- And would ms just be the spin?
- Yes, ms is the electrical spin quantum number.
