Study Notes
Chemical Bonds and Related Terms
- Electron Dot Diagram: Visual representation of an atom illustrating valence electrons using dots.
- Ion: An atom that carries a net electric charge, either positive or negative.
- Cation: Specifically, an ion with a positive charge, often formed by losing electrons.
Types of Chemical Bonds
- Chemical Bond: The force responsible for holding atoms or ions in a unified structure.
- Ionic Bond: This bond occurs between cations and anions, resulting from the electrostatic force of attraction.
- Covalent Bond: Involves the sharing of a pair of valence electrons between two atoms.
- Polar Covalent Bond: A special type of covalent bond where electrons are shared unevenly between atoms, leading to partial charges.
Molecular Structures and Compounds
- Chemical Formula: Notation that expresses the composition of a compound, detailing the types and ratios of atoms present.
- Molecule: A group of atoms bonded covalently, resulting in a neutral entity.
- Polyatomic Ion: A cluster of atoms bonded covalently that carries an overall charge, functioning as a single unit.
Solid Structures and Bonds
- Crystals: Solids characterized by a repetitive lattice arrangement of particles, giving them distinct geometric shapes.
- Metallic Bond: This bond is formed through the attraction between metal cations and delocalized, shared electrons, granting metals their properties.
- Alloy: A combination of two or more elements, with at least one being a metal, often created to enhance certain properties.
Additional Ion Information
- Anion: An ion that possesses a negative charge, resulting from the gain of electrons.
