Quantum numbers of atoms in a given state "(number^number)letter"
1. The problem statement, all variables and given/known data
An atom is in the state 42F.
Write down the values of n,l,s and j.
2. Relevant equations
3. The attempt at a solution
I'm having problems with s and j. I know j=l+s, does one have to take parity into account?
I'm not even sure that the 2 I attempted are correct.
If someone could just tell me the method of working out the different quantum numbers when given a state such as above it would help me a lot.
Any help would be appreciated thanks!
