Study Notes
Diatomic Molecules
- Diatomic molecules consist of two atoms bonded together.
- Only seven elements in the periodic table naturally exist as diatomic molecules.
List of Diatomic Elements
- Diatomic elements symbolized as HOBrFINCl (pronounced hober-finkle):
- H (Hydrogen)
- O (Oxygen)
- Br (Bromine)
- F (Fluorine)
- I (Iodine)
- N (Nitrogen)
- Cl (Chlorine)
- Mnemonic to remember names: "I Never Bring Classwork Home On Fridays"
Subscripts in Diatomic Elements
- Diatomic elements have a subscript of 2 when they exist alone (e.g., H₂ for hydrogen).
- In compounds, no subscript is used for diatomic elements (e.g., HCl for hydrochloric acid).
- Exception: sometimes more atoms are required for a neutral compound, such as H₄C, where hydrogen needs four atoms to balance carbon's +4 charge.
Individual Diatomic Elements
- Nitrogen: Exists as N₂.
- Oxygen: Exists as O₂.
- Fluorine: Exists as F₂.
- Chlorine: Exists as Cl₂.
- Bromine: Exists as Br₂.
- Iodine: Exists as I₂.
- Hydrogen: Exists as H₂.
