Quantum number and electronic configuration

AI Thread Summary
The discussion revolves around determining the quantum numbers for carbon's electronic configuration, which is 1s² 2s² 2p². Participants clarify that the question requires both the electronic configuration and the corresponding quantum number combinations. Key quantum numbers include the principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (ml), and spin quantum number (ms). The importance of ml, which describes the orientation of the orbital, is emphasized as it relates to l. Overall, the conversation highlights the need to consider all quantum numbers when analyzing electronic configurations.

Homework Statement


The problem is: find all possible quantum numbers for each electronic configure of carbon.


2. The attempt at a solution
I don't quite understand what the question is asking. Does it ask first write down the electronic configuration and write down all quantum number combination? Like the following

The electronic configuration for carbon is 1S^2 2S^2 2P^2

1) n=1, l=0
because 2s+1=2 => s=1/2
ms = 1/2, -1/2

2) n=2, l=0 or 1

so,

n=2, l=0, ms=1/2, -1/2

n=2, l=1, ms=1/2, -1/2

Looks good for the most part, but there is also ml to consider.

ml? What's that?

You can think of it as describing the orientation of the orbital, and is related to l which describes the orbital's shape.

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
