Quantum Numbers

Blog Post #4
February 28, 2016

Our third lecture consisted of quantum numbers. These rules closely correlate with the electron configuration rules as well. 

1.) Principle Quantum Number (n): This is the value of the principal energy level. 
2.) Angular Momentum Quantum Number (1): this number is determined from what sublevel it lies in.
3.) The Magnetic Quantum Number:
Runs from -1 to 1, mainly focused on the orbitals. 
4.) The Spin Quantum Number: This number +1/2 for the first electron in an orbital and -1/2 for the second electron in an orbital.

  1. Quantum numbers were confusing at first, but as I did practice problems with them it got better.

  2. Thank you for the recap on quantum numbers! The way you organized the data was extremely helpful, and I might even print it off!
