Energy Level Diagrams

Electrons are arranged so that the element has...

• ...the lowest amount of energy, which is called the excited state configuration

• ...the lowest amount of energy, which is called the ground state configuration

• ...the highest amount of energy, which is called the excited state configuration

• ...the highest amount of energy, which is called the ground state configuration

The following statement describes which filling rule: There must be one electron in each orbital in a subshell, before two electrons are placed in an orbital.

• Hund's Rule

• Aufbau

• Pauli Exculsion

The following statement describes which filling rule: Two electrons that occupy the same orbital need to have opposite spins.
