Study Notes
Definitions and Key Concepts
- Atom: Basic unit of matter, neutral particles that can combine chemically.
- Compound: Combination of at least two atoms, chemically bound in a definite arrangement.
- Molecule: Group of two or more atoms bonded together.
- Ion: Charged particle that results from losing or gaining electrons. Can be monoatomic (single atom) or polyatomic (group of atoms).
Types of Atoms and Ions
- Monoatomic Ions: Have one atom, can be cations (positively charged) or anions (negatively charged). Examples include Na+, Ca2+, Cl-.
- Polyatomic Ions: Comprised of two or more atoms with a net charge, such as NH4+ (ammonium) or SO42- (sulfate).
- Diatomic Ions: Molecules consisting of two atoms, like O2 or N2.
Oxidation States
- Transition metals display multiple oxidation states, for example:
- Copper: Cu+ (lower) and Cu2+ (higher).
- Iron: Fe2+ (ferrous) and Fe3+ (ferric).
Naming Ions
- Classical Method: Utilizes Latin names and suffixes.
- Lower oxidation #: “-ous”
- Higher oxidation #: “-ic”
- Stock Method: Uses the English name followed by a Roman numeral to indicate oxidation state.
Common Polyatomic Ions
- Cations: NH4+ (ammonium), H3O+ (hydronium).
- Anions: OH- (hydroxide), SO42- (sulfate), CO32- (carbonate).
Chemical Formulas
- Molecular Formula: Indicates the actual number of atoms in a molecule (e.g., C6H12O6).
- Ternary Ionic Compounds: Formed from a monoatomic cation with a polyatomic anion or the reverse. Example: NaNO2 for sodium nitrite.
Acids and Bases
- Binary Acids: Formed from hydrogen and a monoatomic anion. Naming depends on state:
- Gaseous: hydrogen chloride (HCl).
- Aqueous: hydrochloric acid.
- Oxyacids: Derived from polyatomic ions:
- Lower oxidation: “-ite” becomes “-ous” acid (e.g., HNO2 is nitrous acid).
- Higher oxidation: “-ate” becomes “-ic” acid (e.g., HNO3 is nitric acid).
- Bases: Formed from a cation with OH- (e.g., NaOH for sodium hydroxide).
Molecular Compounds
- Prefixes are used in naming covalent compounds:
- 1: mono-, 2: di-, 3: tri-, 4: tetra-, etc.
- Examples include:
- CCl4 as carbon tetrachloride.
- P2O5 as diphosphorus pentoxide.
Exercises and Application
- Practice naming and writing formulas for chemical compounds, both ionic and molecular. Include real examples to reinforce learning.
- Explore exercises involving combining ions and applying proper naming conventions for acids and bases.
Importance of Chemical Nomenclature
- Understanding the type of atom, compound, or ion is crucial for accurate chemical writing and naming, which aids in communication within the scientific community.
