Study Notes
Diatomic Molecules
- Diatomic molecules are composed of two atoms bonded covalently.
- Seven elements exist as diatomic molecules: Hydrogen (Hâ‚‚), Oxygen (Oâ‚‚), Fluorine (Fâ‚‚), Bromine (Brâ‚‚), Iodine (Iâ‚‚), Nitrogen (Nâ‚‚), and Chlorine (Clâ‚‚).
Molecular Elements (Non-Diatomic)
- Three elements have more than two atoms per molecule: Ozone (O₃), Phosphorus (P₄), and Sulfur (S₈).
Exceptions to Naming Rules
- Some molecules, despite not fitting the diatomic rule, are common and have specific names:
- Water (Hâ‚‚O)
- Methane (CHâ‚„)
- Ammonia (NH₃)
- Hydrogen peroxide (Hâ‚‚Oâ‚‚)
