Polymer: Molecules and Extended Structures Study Guide

Atomic Composition

The types and quantities of atoms that make up a molecule or compound, determining its chemical properties and reactivity.

Chemical Structure

The arrangement of atoms within a molecule, including the bonds between them, which influences the substance's physical and chemical behavior.

Molecule

A group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Extended Structure

A structure consisting of repeating units or patterns that extend in three-dimensional space, such as crystals or polymers.

Chemical Bond

A lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds. Types include ionic, covalent, and metallic bonds.

Model

A representation of an object, system, or concept that helps explain its properties and behavior.

Crystal

A solid material whose atoms are arranged in a highly ordered, repeating pattern.

Graphite

A form of carbon where atoms are arranged in layers, allowing them to slide over each other, giving it lubricating properties.

Diamond

A form of carbon where atoms are arranged in a three-dimensional tetrahedral structure, resulting in a hard and rigid substance.

Subunit of an Extended Structure

A smaller, repeating unit that comprises an extended structure, often displaying specific symmetry or organization.

Bond Angles

The angle between two bonds in a molecule, which affects its overall shape.

Bond Lengths

The distance between the nuclei of two
