Study Notes
Compounds and Their Definitions
- NF3 is known as Nitrogen Trifluoride, a compound with nitrogen and fluorine.
- Iron (III) Oxide has the chemical formula Fe2O3, indicating its oxidation state.
- A compound forms when two or more elements chemically combine, resulting in a new substance.
Oxidation Numbers
- Oxidation numbers help determine how many electrons an atom gains or loses during compound formation.
- To assign oxidation numbers: identify element symbols, assign based on Roman numerals for metals and the periodic table for nonmetals.
- Follow a crisscross method for oxidation numbers, reducing only if necessary.
Types of Bonds
- Ionic bonds occur when metals bond with nonmetals or when metals bond with other metals, typically resulting in gaining or losing electrons.
- Covalent bonds form between nonmetals, where they share electrons.
Common Compounds and Their Formulas
- Sodium Chloride is represented by the formula NaCl.
- Iron (III) Nitride is denoted as Fe3N3, showcasing the combination of iron and nitrogen.
- Calcium nitride is represented as Ca3N2, formed from calcium and nitrogen.
- Chromium Phosphide has the formula Cr3P2, illustrating the bond between chromium and phosphorus.
- Dinitrogen Trioxide is expressed as N2O3, a compound with nitrogen and oxygen.
- Carbon Monoxide is represented by the formula CO, indicating a compound of carbon and oxygen.
- Tetrafluorine Dioxide is denoted as F4O2, indicating four fluorine atoms bonded to two oxygen atoms.
Properties of Ionic Compounds
- Ionic compounds typically form crystalline structures.
- They have high melting points due to strong electrostatic forces between ions.
- Ionic compounds can conduct electricity when dissolved in water or melted, allowing movement of ions.
