Quantum Numbers (Sounds Fancy, not that hard)

Today we learned about Quantum numbers which sound scary but really its just the identity of the atom and its electrons. Its just a few simple rules you have to remember about it for example if the electron config is 2P3 you take the first number and move it over so its 2 then the next would be the P which is equal to a 1 (S=0 P=1 D=2 F=3) and then it gets a little tricky you have to make an Orbital map. So in this case  it would be a 1 and then the election ends with a positive spin so its +1/2. So the quantum numbers would be 2, 1, 1, +1/2.
