Study Notes
Cations and Anions in Binary Ionic Compounds
- Cations (positive ions) are formed from metal atoms, which lose electrons to achieve a stable electronic configuration.
- Anions (negative ions) are formed from non-metal atoms, which gain electrons to achieve a stable electronic configuration.
- In binary ionic compounds, anions are formed from non-metal atoms that gain electrons to achieve a stable electronic configuration.
- When a non-metal atom becomes an anion, its name changes to have the suffix "-ide" (e.g., chlorine becomes chloride).
Polyatomic Ions and Naming Rules
- Polyatomic ions are composed of two or more atoms that are covalently bonded together.
- In simple ionic compounds, cations are named using the same name as the parent element.
- Non-metals becoming anions are named using the suffix "-ide" (e.g., chlorine becomes chloride).
- A Roman numeral is needed in naming compounds with transition metals to indicate the charge of the metal ion.
- In naming ionic compounds with transition metals, the Roman numeral is placed in parentheses after the name of the metal.
Specific Compounds
- The compound NaCl (sodium chloride) is formed from sodium (Na) and chlorine (Cl), where the name of the non-metal Cl is changed to chloride.
- Iron (III) oxide consists of iron (Fe) and oxygen (O) ions, with the Roman numeral III indicating the +3 charge of the iron ion.
- The compound formed when Sodium reacts with Nitrate is Sodium nitrate.
- Lead (III) sulfate consists of lead (Pb) and sulfate (SO4) ions, with the Roman numeral III indicating the +3 charge of the lead ion.
Exceptions
- The polyatomic ion ammonium (NH4+) is an exception to the general rule for naming polyatomic ions.
