Question 1.
What principle states that electrons fill orbitals starting from the lowest energy level?
Show hintHide hint
Think of the order in which you fill layers in a structure.
Question 2.
What does the Pauli Exclusion Principle state?
Show hintHide hint
Consider how many electrons can share space in an orbital.
3Question 3.

Show hintHide hint
Remember to add electrons sequentially according to available orbitals.
Question 6.
Choose an element with unpaired electrons in its electron configuration, explain your choice referencing Hund's Rule.
Show hintHide hint
Check the 2p orbitals for unpaired options.
