I don't understand why there are 2 dashed values in this table: http://en.wikipedia.org/wiki/Quantum_number#Quantum_numbers_with_spin-orbit_interaction. I have that j=l+s,l+s-1,...,|l-s|. So let's take #1 of the table. They give l=1 and we know that s=1/2. Thus j=l+s=3/2 or j=l-s=1/2. Why...

I need to define some "Tables" in Mathematica, in which some elements contains their own item number, like the following example below : A := {a, b, 3 c, d} B := {1, b, c, d} C := {a, b, c, 4, d, e} D := {a, 2, c, d, 5, g} How can I do this ?

So for my inorganic class we need to know the periodic table by heart, as we will not be getting one on our tests. While memorizing groups and periods in order doesn't hold that much practical sense (it would be much better to be able to just recall any element by it's number along with it's...
