[SOLVED] Quantum Numbers What is the difference between using J and l for quantum numbers? I have some lecture notes that aren't fully explained. It was talking about rotational transitions for diatomic molecules, and said the energy of a photon going from level J to level J-1 is...

Is it generally true that the ground state of a given quantum system corresponds to the lowest quantum numbers? If so, how do we know this?

I need help with this problem :) Problem: Give the quantum numbers (n, l, ml, ms) for each electron in one neutral carbonatom in ground state. My solution: I look at a table to get the electron configuration and for a carbonatom i get 1S^2 2s^2 2p^2 For s n=1, l=0, ml=0, ms=+-1/2...

A hydrogen atom is initially in the 5d state. It makes a single transition to the 4f state. List all the possible transitions that have occurred in terms of the four quantum numbers. List all

For angular momentum quantum numbers j, l, and s must it be true that m_s, m_l < m_j ? It would seem that it is true because I assume that m_s +m_l = m_j , but I have not actually seen that written down anywhere and am curious. Thanks.

Hi, I have a question about the discussion of the free-electron (Fermi) gas in my solid-state physics notes. In the free electron model, you basically have particles in a box, and the state of any particle is described by four quantum numbers, nx, ny, nz, and ms, the spin magnetic quantum...

Homework Statement a)write a ground state electron configuration of for the arsenic atom b)give a possible set of quantum numbers for each of the three outermost electrons of the arsenic atom i know how to get the ground state, but i have no idea how to get the quantum number for each...

Hey guys, this isn't really homework but will help me on the exam and the homework too. We are working in the book, where you just get to electron structure, orbitals, configurations, etc. The part that I need help with is Quantum Numbers. My book has: n(principal energy levels)...

Does anyone know how to prove, mathmatically, that the principle quantum number squared equals the maximum number of electon orbitals?any help would be appricated! n^2=max # electron orbitals

Hey, I have two matrices A and B which commute. For A I have 1,-1,-1 and for B I have 1,2,2. I am asked to find the quamtum number for the three states. How to find the quantum states from the eigenvalues. It is further said that it is possible to find the eigenvectors from the quantum...

The question isn't exactly like this but this is the jist of it: Give the values of the quantum numbers associated witht he following orbitals: 2p, 3s, and 5d. I ,frankly, do not understand what they are asking for. So can anyone explain this for me. Thanks.

Good evening scholars! i just had a couple of questions about QNs. ok so the problem says: Give the sets of {n, l, m, s} for the electrons in: a) 4p^2 b) 6s^2 i just want to see if I'm on the right track. here's what i put for the first one (a): n= 4 l= 1 m= -1, 0 s= +/- 1/2...

Hi i was wondering what quantum numbers can change the energy of a electron within a atom. I thought it would be n and l since its the energy and sub energy numbers, but i was wrong. Can someone explain it in some more deatail please?

how to create "good" quantum states from "good" quantum numbers? I think I am finally understanding what the "good" quantum numbers are in degenerate perturbation theroy. Basically, given a perturbation H', if [H', L^2] = [H', S^2] = [H', J^2] = [H', Jz] = 0, then l, s, j, and mj are the...

What is the physical significance of the various quantum numbers like (l,m,s,j, etc)that are used to describe any system.

Hi, What are the 4 quantum numbers for the last electron in the Al atom? I know how to get the primary quantum number and the spin quantum nmber, but I do not now how to get the secondary/azmuthal quantum number, and the magnetic quantum number. The book gives the secondary/azmuthal...

Which are (basic?) quantum nubers of fundamental particles? I am having problems becouse a lot of expresions are used on sites on the web: el. charge, color charge, mass, taste, spin, barion & lepton number... to many :eek: :confused:

hi all, What is quantum number? I know a bit about quantum number but i am not clear about it so can anyone please help me?. -Benzun, All for God.
