8. Quantum Numbers Board Problems
Work with your table to solve the problems Ms.Ose puts on the PowerPoint.

9. Can an e- be described by the following set of quantum numbers?
n=7, l=3, ml= +3
All the quantum numbers are allowed
values.

10. Can an e- be described by the following set of quantum numbers?
n=3, l=1, ml=-3
Not possible.
The value of ml must be in the range
-l to +l

11. Replace the ? Mark with an appropriate quantum number.
n=3, l=1, ml=?
n=4, l=?, ml=-2
n=?, l=3, ml=?

12. Can an e- be described by the following set of quantum numbers?
n=2, l=1, ml=-2
n=3, l=2, ml=+2
n=4, l=3, ml=+3
n=5, l=2, ml=+3

13. Writing Quantum Numbers
You can identify the quantum numbers for any electron in an element
Start by writing out the the electron configuration and orbital diagram for the element
Locate the electron in the orbital diagram that you are solving the quantum number for
Determine the 4 quantum numbers

14. Hydrogen’s electron Write electron configuration Draw orbital diagram
ml= 0
ms= +1/2

15. Helium’s second electron
Write electron configuration
Draw orbital diagram
n= 1
l= 0
ml= 0
ms= -1/2

16. Lithium’s third electron
Write electron configuration
Draw orbital diagram
n= 2
