Study Notes
Exceptions to the Octet Rule
- Some elements can violate the octet rule in a Lewis structure, including Be, B, and P.
- Dative bonds (also known as coordinate covalent bonds) do not necessarily follow the octet rule.
- XeF2 is a molecule that violates the octet rule in its Lewis structure.
- In a Lewis structure, 8 electrons are typically shown around each atom.
- P, S, and Cl can exceed the octet rule in a Lewis structure, having more than 8 electrons.
- A dashed line between two atoms in a Lewis structure represents a dative bond or coordinate covalent bond.
