Quantum numbers
« on: May 04, 2018, 01:02:33 PM »
Would this exercise on quantum numbers be okay? I just don't know if L can be equal to - 1.

Given the following quantum number sets:
a) (2, -1, 1, 1/2)
b) (3, 1, 2, 1/2)
c) (2, 1, -1, 1/2)
d) (1, 1, 0, -1/2)
Explain whether or not it is possible for electrons with such quantum numbers to exist in an atom.

My answer:
a) n=2, l=-1,0,1, m=-1,0,1, s=1/2, -1/2
b) n=3, l=0,1,2, m=-1,0,1
c) n=2, l=0,1, m=-1,0,1, s=1/2, -1/2
d) n=1, l=0, m=0, s=1/2, -1/2

Thanks

L can't equal negative numbers
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
