### Quantum Numbrrs

Is there a trick to quantum numbers, or do you just have to memorize them? Also why does the d-orbital not follow the pattern?

You must memorize them. What pattern are you referring to?

I think maybe the pattern they are referring to is how the 3d orbitals get filled up before the 4s after atomic number 20, even though according to the pattern, 3d is after 4s. But they're filled up because they're lower energy, so it makes sense that the lowest energy level orbitals get filled up first.
