HONORS UNIT 8 - Liquids and Solids

Solid

state of matter with a fixed shape and fixed volume

Liquid

state of matter with a fixed volume but not a fixed shape

Gas

state of matter with no fixed shape or volume

intramolecular forces

forces within a molecule, like covalent bonds

intermolecular forces

forces between different molecules, like london dispersion forces

London dispersion forces

an intermolecular attraction resulting from the constant motion of electrons and the creation of temporary dipoles

Dipole-Dipole Forces

an intermolecular force that is in POLAR molecules only

Hydrogen Bonding

the strongest intermolecular force

Network covalent

non metal plus nonmetal, no hydrogen

Amorphous

usually given name, plastic or glass smth like that

Metallic

metal plus metal

molecular solid

non metal plus non metal

ionic solid

metal and a nonmetal

Normal Boiling point

temperature where the vapor pressure equals the standard pressure on the vapor pressure curve 760

This type of solid is a nonconductor and has low melting/boiling points

Molecular Solid

This type of solid conducts electricity only when dissolved in water or molten

Ionic Solid

This type of solid is malleable, ductile and is an excellent conductor of electricity

Metallic Solid

This type of solid has VERY high melting points and boiling points

Network Covalent Solid

This type of solid is without shape and formed when a molten substance cools too quickly

Amorphous Solid

Crystalline Solid

solids that have an orderly, geometric 3-D structure
