METALS, NONMETALS, AND METALLOIDS (VOCABULARY)

Luster The way an object reflects

light; Examples

ShineyDullMetalicWaxy

Malleability How well an object can be

hammered into thin sheets.

ExamplesFlattened pennyAluminum canTin foilAluminum foil

Conductivity How well an object allows

electricity to move through.

Ductility Can be stretched into wire.

Magnetism Attracted to or repelled by a

magnet.

Sonorous Produces a sound when struck with

another object.

Metals Elements which have

physical properties such as good conductivity, shiny luster, malleability and ductility.

Nonmetals Elements which have

physical properties such as no conductivity (an insulator), dull luster, and brittleness (will break).

Metalloids Elements which can have

both properties of metals and nonmetals.

Also may be called a semi-conductor.

Density Formula Density = mass/volume D=m/v (I density)

Volume Formula

V = L x W x H

Volume=length x width x height

Water Displacement A method used to calculate

the volume of an irregular shaped object.
