Question

I need help understanding quantum numbers. The specific question I am working on right now is asking for the set of 4 quantum numbers for the highest energy electron in Te. I have no idea how to even begin the question. Please help!

Answer 1

Well @Adri17 consider if we have carbon which has 6 electrons.

there are four different quantum numbers:
n = the principle quantum number that's the energy level we're at. like going down a group the energy levels get higher, makes sense because there are more electrons.
l = tells us the shape of our orbitals.
mL = the orientation this can be from -l to 0 to positive l but never greater than l
the fourth quantum number is the spin which is +1/2 or -1/2 corresponds to the spin of the electron whether it's spin up or spin down.

ill show you the quantum numbers for carbon .

Answer 2

let's take carbon for example
