Electronic Structure of Atoms

Read each question carefully and answer to the best of your ability. Show all work where applicable.

1. Which of the following describes the most probable location of an electron in an atom?

2. What is the maximum number of electrons that can occupy the third principal energy level (n=3)?

3. The   principle states that an electron occupies the lowest energy orbital that can receive it.

4. According to Hund's rule, orbitals of equal energy are each occupied by one electron before any one orbital is occupied by   electrons.

5. The quantum number that describes the orientation of an orbital in space is the   quantum number.

6. Write the full electron configuration for a neutral atom of Oxygen (O).

7. Explain the Pauli Exclusion Principle.

8. An electron in a 3p orbital has a higher energy than an electron in a 3s orbital.

9. All orbitals within a given subshell have the same energy.

Match each term with its definition.
