Be able to list the values of 4 quantum numbers associated with a designated orbital? This is what my study guide for my chemistry final says, and I'm not sure what it means. Could you explain/ perhaps give me a sample question?

    N = your principle quantum number this is associated with the energy of your orbital. L = your shape l can be an integer greater than 1 Ml = the number of orientations from -l to positive l including 0 S = the spin of your orbital which is. +1/2 and -1/2 I think this corresponds to whether your electron is spin up or spin down.

    Let's try a problem Say you have N = 1 l = 0 mL = 0 s = +1/2 Well first we know that l = 0 means that it's spherical. N = 1 means our lowest energy level. mL means one orientation of that orbital is available and the +1/2 means where our electron is I spin up. That would be a 1 s orbit which would be a sphere.

    FYI Minimum energy requirement for your orbitals S orbitals start at n =1 P orbitals start at n = 2 D orbitals at n = 3 f orbitals at n = 4 So in each orbital we have 2 electrons. I believe. To find how many orbitals we have for each of those we know that each orbital must have 2 electrons. S orbital = 2 electrons/2 = 1 orientations P orbital = 6 electrons/2 = 3 orientations D orbital = 10 electrons/2 = 5 "." F orbital = 14 electrons/2 = 7 "."

    So a p orbital starts at n = 2 and has 3 orientations Px PY and PZ each can hold 2 electrons for a maximum of 6 electrons.

    Here's another practice question for you: What are all the quantum numbers of the valence electrons on Nitrogen?
