Study Notes
Diatomic Molecules Overview
- Diatomic molecules consist of two atoms bonded together.
- There are 7 diatomic elements on the periodic table.
List of Diatomic Elements
- Diatomic elements are represented by the acronym "HOBrFINCl":
- Hydrogen (H)
- Oxygen (O)
- Bromine (Br)
- Fluorine (F)
- Iodine (I)
- Nitrogen (N)
- Clorine (Cl)
Naming Convention
- The mnemonic "I Never Bring Classwork Home On Fridays" helps recall the names of the diatomic elements:
- Iodine
- Nitrogen
- Bromine
- Chlorine
- Hydrogen
- Oxygen
- Fluorine
Subscripts for Diatomic Elements
- When an element exists independently as a diatomic molecule, a subscript of 2 is used (e.g., H₂).
- In a compound, the diatomic element does not typically show the subscript (e.g., HCl is hydrogen chloride).
- Exception: If more atoms are required for neutrality in a compound, subscripts must reflect this (e.g., H₄C for hydrogen with carbon).
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.
