Question 19

What are the guidelines for filling electrons (3)

Answer 19

The Pauli exclusion principle
The Aufbau principle
Hund’s rule

Question 20

What does the Pauli exclusion principle state.

Answer 20

Each orbital can contain a maximum of two electrons, with each electron having a different spin

Question 21

What does Aufbau’s principle state

Answer 21

Electrons will occupy lower energy orbitals first

Question 22

What does Hund’s rule state

Answer 22

Each orbital sub level must contain an electron before electrons can be paired.
