Chapter 5 Structure and Properties of Materials
Compound
Two or more elements that are chemically combined
Formed from a chemical reaction
It has a fixed ratio
Has different properties from its constituent elements
Has a fixed melting and boiling point
Mixture
Two or more elements and/or compounds that are not chemically combined
Formed usually from physical mixing
Has no fixed ratio
Usually has similar properties to its constituent substances
Melts and boils over a range or temperatures
Element
Mostly naturally occurring
Melting and boiling points are both fixed
Ionic compounds have melting and boiling points
Ionic compounds are physically hard but brittle
Ionic compounds are often soluble in water but insoluble in organic solvents
An alloy is a mixture of a metal with one or more other elements
Pure metals are malleable and ductile
Metals and alloys usually high melting and boiling point
They are good conductors of heat
Metals and alloys are good electrical conductors
