Note from the author:

This assignment will not show you if you are correct or incorrect. After you submit it, it will tell you your overall score.
This is a mastery assignment, meaning that you must get an 80% or above in order to pass. 

Use the information that you have been taught regarding electron configurations, energy levels, orbitals, ground state configurations, and electrons (numbers and orientation) to help you answer each of these.

If may take this as many times as needed, until Thursday @3:45 PM to pass this.
