### Sapling Question Number 7

What do the n and l represent in the sapling? and How are s, p, d, and f separated in groups?

n is the Principal Quantum Number, and n refers to the energy levels (e.g. when it's 1s, n = 1 or when it's 3d, n = 3).
l is the Angular Momentum Quantum Number, and l refers to the shape of the orbital. l can assume any value between 0-(n-1). (e.g. for n = 3, the possible values of l = 0, 1, 2.) l = 0 corresponds to s-orbitals, l = 1 corresponds to the p-orbitals, l = 2 corresponds to the d orbitals, l = 3 corresponds to the f orbitals. Higher values of l can correspond with higher orbitals such as g-orbital and h-orbital, but we only need to be concerned with l = 0,1,2,3. l is used to determine the orbital angular momentum,

Hi, I was wondering if you could explain what m1 is as well? Thank you

M is the magnetic quantum number which specifies which individual orbitals to my understanding. There are (2l+1) orbitals. For instance for n=3 l=2 m can equal -2,-1, 0, 1, 2. Up to two electrons fit in each orbital.
