You can PM my for any stats and methodology related questions :hillarybiz:
 
i can help anyone with calculus 1/2/3, electrical engineering foundations, computer science and engineering physics/science. also know signals/communication systems design, discrete maths and pretty much anything but chemistry and biology in stem.

just pm me any time

Bio and chem? Those are the easiest ones lmao
 
Anybody do quantum physics here? I'm confused with a question:

6.Assuming magnetic interactions occur what additional quantum numbers arise from the term symbol 3^2S.Such that it follows n^(2s+1)L(Subscript(J))

I thought that magnetic interactions simply affect the fine structures of a system due to it interacting with the quantum spin, however I'm confused if it is asking us to list new J states or do actual new l,ml,s,ms values occur.

thx :p

Sorry I'm going to use my limited knowledge of magnetic spin from Chemistry, this will likely be wrong but hopefully it gives you ideas in the right direction:

We're dealing with an electron in the 3s2 energy state, so using the four quantum numbers:
n=3 energy level
l =0 because s subshell
m=0 because still s subshell
s= can be +/- 1/2 for any electron (spin up or down)

Now the question asks you to determine other possible quantum numbers based off of this
n^(2s+1)L(Subscript(J))

Doing a Wikipedia search:
J=L+S because s subshell is more than half-filled (has 2/2 electrons in it)

Where L= 0 because all magnetic quantum numbers are 0 for the electrons (in s subshell) in spectroscopic notation it is "S"

and

S=0 because the spin quantum number can be +1/2 or -1/2 for each electron. Since there are no unpaired electrons S=0

So J=0

n^(2s+1)L(Subscript(J))

3^(1)S(Subscript(0))

ye I got that, the question was how does magnetism change the quantum states.I think I got it tho.J and S changes due to the introduction of fine structure.

Since this thread is mostly Science and Maths based I don't know how much help I can get but if anyone knows how to maximise marks in 16 markers, 24 markers and even higher mark questions for A Levels it would be appreciated. Things like structuring etc.

Thanks

Waryaa just clocked I'm pretty much at the same stage as you although I'm taking a gap year currently
