quantum numbers and orbital planes
Can someone explain how we are supposed to get ml quantum numbers (the third quantum number) again, I don't really understand how I know which number it is, especially if i am given l already.

Re: quantum numbers and orbital planes
Also, does someone understand how Lavelle labeled which axis were used in the second to last example in today's lecture?
The example was:
n=2, l= 1, ml=-1 and he said the answer was that the electron was in 2px state. How did he know it was x?

Re: quantum numbers and orbital planes
the "ml" quantum number gives the relative orientation of the electron in the specific sub-shell. We derive the "ml" number from the "l" number, by following the given values "ml" can be, which are "l","l-1",or "-l". This means that if l were 1, ml can be 1, 0, or -1.

Re: quantum numbers and orbital planes
In response to your second post, the 3 ml values are arbitrary. Basically, ml can be 3 values. If l is 1, ml can be 1,0,-1. These values correlate to the x,y,z planes. Since the values are arbitrary, the x axis can be represented as either 1 or -1. So for the ml=-1, Dr. Lavelle called chose -1 to describe the x axis. Hopefully this makes sense.

In lecture it was written "l", "l-1" ...-1 so I was assuming it could be any number in between l-1 and -1 so i was extremely confused. But great thank you!
