What is the total number of states?

Homework Statement

The ρ- meson has a charge of -e, a spin quantum number of 1, and a mass 1507 times that of the electron. The possible values for its spin magnetic quantum number are -1, 0, and 1. Imagine that the electrons in atoms were replaced by ρ- mesons. Select all of the following which are possible sets of quantum numbers (n, l, ml, s, ms) for ρ- mesons in the 2p subshell.

What is the total number of states?

Homework Equations

n = 2
l = 1
ml = -1, 0, 1

The Attempt at a Solution

2 1 1 1 -1
2 1 1 1 0
2 1 1 1 +1
2 1 0 1 -1
2 1 0 1 0
2 1 0 1 +1
2 1 -1 1 -1
2 1 -1 1 0
2 1 -1 1 +1

Total states = 9 (?)

Do I also count the 2s states or is this question asking for 2p only? I'm confused. Any help is greatly appreciated, thank you!

Looks good. The question does specifically say 2p.

The total number of states for ρ- mesons in the 2p subshell would be 9, as there are 9 possible combinations of quantum numbers (n, l, ml, s, ms) listed. However, it is important to note that this is assuming that the question is only asking for states in the 2p subshell and not including the 2s states. If the 2s states were also included, the total number of states would be 18, as there are also 9 possible combinations for the 2s subshell. It is always important to clarify the scope of a question to ensure the correct answer is provided.
