Study Notes
Diatomic Molecules
- Diatomic molecules are molecules composed of two atoms bonded covalently.
- Seven elements exist as diatomic molecules: Hydrogen (H₂), Oxygen (O₂), Fluorine (F₂), Bromine (Br₂), Iodine (I₂), Nitrogen (N₂), and Chlorine (Cl₂).
Non-Diatomic Molecular Elements
- Ozone (O₃), Phosphorus (P₄), and Sulfur (S₈) are molecular elements that are not diatomic.
Exceptions to Naming Rules
- Some exceptions to the naming rules for simple covalent compounds include: Water (H₂O), Methane (CH₄), Ammonia (NH₃), and Hydrogen Peroxide (H₂O₂).
