Octet Rule

Definition

A chemical rule of thumb that states atoms tend to combine in such a way that they each have eight electrons in their valence shells, making them as stable as noble gases.

Valence Electrons:

The electrons present in the outermost shell of an atom which take part in bonding. These are the "items" you're packing into your suitcase!

Lewis Dot Structure:

Diagrams that show the bonding between atoms and lone pairs of electrons that may exist in a molecule. It’s like a map showing where all your items (electrons) are packed inside your suitcase (atom).

Noble Gases:

Elements with full electron shells which make them very stable and unreactive. They’re like perfectly packed suitcases ready for any trip!
