The Octet Rule states that

• electrons will fill in lower energy first before filling higher energy levels.

• Electrons in the same orbital must have opposite spins.

• Electrons will fill oprbital singly first before they share an orbital.

• Atoms tend to achieve the electron configuration of a noble gas in their outermost energy level by forming chemical bonds.
