METALS, NONMETALS, AND METALLOIDS

(VOCABULARY)

Luster

The way an object reflects light;

ExamplesShineyDullMetalicWaxy

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.
