Polymer: Molecules and Extended Structures Study Guide

This set of flashcards covers key concepts related to atomic composition, chemical structure, and the nature of molecules and extended structures.

Atomic Composition

The types and numbers of atoms present in a molecule.

Chemical Structure

The arrangement of atoms within a molecule, including the bonds between them.

Molecule

A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Extended Structure

A large arrangement of multiple molecules or atoms in a repeating pattern or lattice.

Chemical Bond

The attraction between atoms that allows the formation of chemical compounds.

Model

A representation of a molecule or structure that helps visualize its composition and arrangement.

Crystal

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

Difference in Molecule Properties

Two molecules with the same number of atoms can differ in shape and arrangement, leading to different physical properties (e.g., graphite vs. diamond).

Subunit of Extended Structure

A repeating unit within a larger extended structure, often identifiable in its molecular arrangement.

Atomic Composition Example

The specific atoms (e.g., C, H, O) in a molecule and their quantities.

Chemical Structure Example

The specific arrangement of atoms within a molecule, often depicted in diagrams.
