Study Notes
Naming Ionic Compounds
- Binary ionic compounds are named by listing the cation first, followed by the anion.
- The names of binary compounds conclude with the suffix -ide.
Ionic Compound Examples
- Sodium Iodide is represented as NaI.
- Iron(III) Bromide is represented as FeBr3, indicating a cation with variable charges.
Roman Numerals
- A Roman numeral is included in the name of a cation when the cation possesses more than one ionic charge.
Polyatomic Ions
- Compounds that contain polyatomic ions ending in -ite or -ate have polyatomic anions with oxygen present.
- Sodium Hydroxide (KOH) and Sodium Dichromate (Na2Cr2O7) are examples of ionic compounds featuring polyatomic ions.
Chemical Formula Requirements
- The net ionic charge of an ionic compound formula must equal zero, ensuring charge balance.
- Anions that carry oxygen typically end in -ite or -ate.
Types of Ions
- Monatomic ions consist of a single atom, while polyatomic ions comprise multiple atoms.
- Transition metals can form multiple charged ions, impacting their naming conventions.
Specific Compounds
- Sodium Chlorate is represented by the formula NaClO3.
- Lead(II) Phosphate corresponds to the formula Pb3(PO4)2.
- Magnesium Hydrogen Carbonate is denoted by Mg(HCO3)2.
