MATTER (SUBSTANCES)M1

CLASSIFYING MATTER

Element - a pure substance

Compound – 2 or more elements chemically combined

Mixture – 2 or more substances physically combined

ELEMENT

MIXTURE

MIXTURE

MIXTURES

Solution – a clear mixture (less than 1nm diameter in it)

Colloid – a cloudy substance (1nm to 1,000 m in diameter)

Suspension – a muddy substance (more than 1,000 nm in diameter)

SOLUTIONS

COLLOIDS

SUSPENSIONS

STATE OF MATTER

Solid – has volume and shape

Liquid – has volume, no definite shape

Gas – no definite volume and shape

CLASSIFY ELEMENTS Metals – solid at room

temperature except mercury (ductile, malleable, good conductors, high boiling point & melting points)

Non-metals – mostly gases (low boiling points & melting points, poor conductors)

Metalloids – have both properties of metal and non-metals

VOCABULARY Ductile – Malleable – Conductor

THE PERIODIC TABLE OF ELEMENTS

METALS

Shiny surface Malleable Ductile Good Heat

Conduction Good Electricity

Conduction High Melting and

boiling point

PROPERTIES

Ductility is the ability for a material to be pulled into a thin wire.

Malleability is the ability for a material to be flattened into a thin sheet.

GOOD VS. POOR HEAT CONDUCTION

NON-METALS

Dull Not malleable Poor Heat

Conduction Poor Electricity

Conduction Low melting and

boiling point Brittle
