Study Notes
Ionic Compounds and Ions
- N3- ion is known as the nitrate ion.
- Aluminum, a group 3A metal, typically forms the ion Al3+.
- Transition metal ions may possess multiple common ionic charges, clarified by Roman numerals indicating the charge in their names.
- Nonmetals in Groups 6A and 7A derive their charges by subtracting 8 from their group number.
Chemical Formulas
- Binary ionic compound formulas are structured with the cation on the left and the anion on the right.
- Lithium is the likely element to form an ionic compound with fluorine.
- Sulfur hexafluoride exemplifies a binary compound.
Acids and Bases
- Acids release hydrogen ions (H+) when dissolved in water.
- Bases yield hydroxide ions (OH-) in an aqueous solution.
- When naming acids, the prefix "hydro-" is utilized if the anion name ends in "-ide".
Molecular Compounds
- Binary molecular compounds consist of two nonmetallic elements.
- The naming of binary molecular compounds incorporates prefixes to denote the number of atoms present for each element.
- All binary compounds, whether ionic or molecular, end with the suffix "-ide".
Polyatomic Ions
- An -ite or -ate ending in a polyatomic ion indicates the presence of oxygen in the formula.
Key Formulas and Names
- Chemical names and formulas must correspond correctly; for example, tin(IV) bromide is represented as SnBr4.
- Sulfurous acid corresponds to the formula H2SO3, derived from the suffix "-ous" when the anion ends in "-ite".
- Hydrosulfuric acid is represented by the formula H2S.
- The ion pair of Fe3+ and O2- forms the compound Fe2O3, while Ca2+ and F- combine to form CaF2.
Proportions in Compounds
- Elements in a chemical compound are consistently combined in the same mass proportion.
- Calcium dihydrogen phosphate is accurately represented by the formula CaH2PO4.
