Hi! So, I understand that n is related to the size and energy of the orbital and is also referred to as the shell. Then, l describes the shape of the orbital and its values can be equal to 0,1,2,...,n-1. When l=0, is corresponds to the s-orbital, when it equals 1, it corresponds to the p-orbital, when it equals 2, it corresponds to the d-orbital, and when it equals 3, it corresponds to the f-orbital. I am confused on the part if n were to equal 5, then a possible value for l could be 4, but I am not sure what orbital that would be in?
Hey Janavi! Right now, there are no elements that contain orbitals with an l value of 4. In fact, the chemistry gets interesting once we get to the f orbitals even. Recently, scientists have finished the 7th row of the periodic table. Maybe soon researchers can get to an l = 4 state.
The quantum number Ms, or spin magnetic quantum number, is either +1/2 or -1/2. If positive the spin is upward and if negative the spin is downward. If the electrons are paired then one will have the quantum number Ms +1/2 and the second will have the quantum number -1/2. If they are parallel however, both will have the same Ms number but no matter what, no two electrons in an atom's configuration are going to have all the exact same quantum numbers. Ms separates out the paired electrons from one another simply by adding the direction of the spin.
