Quantum Numbers Explained
The principal quantum number tells us which energy level an electron occupies. This number must be a whole integer greater than zero (1, 2, 3...) and represents the main electron shells around an atom.
The angular momentum quantum number indicates the subshell or sublevel where the electron resides. For any given n value, l can be any integer from 0 to , representing s, p, d, or f subshells.
The magnetic quantum number specifies which orbital within a sublevel contains the electron. The value of m can be any integer from -l to +l, determining the orbital's orientation in space.
Remember This: Think of quantum numbers as an electron's mailing address: n is the city (energy level), l is the street (sublevel), m is the house number (orbital), and s is the specific resident (electron spin).
The spin quantum number can only be +1/2 or -1/2, representing the electron spinning in one of two possible directions. No two electrons in an atom can have identical sets of all four quantum numbers!

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
