Metals, Nonmetals, and Metalloids
(Vocabulary)
Periodic Table of Elements
A
table in which all the known elements
are arranged by properties and are
represented by one or two letter
chemical symbols.
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 semiconductor.
Luster
The
way a substance reflects
light;
Examples
Shiney
Dull
Metalic
Waxy
Malleability
How
well it can be hammered
into thin sheets.
Examples
Flattened penny
Aluminum can
Tin foil
Aluminum foil
Brittle
 The
tendency to break, snap, or crack
without first bending or changing shape
as a result of application of little force.
Conductivity
How
well it allows electricity
to move through.
Ductility
Can
be stretched into wire.
Magnetism
Attracted
to or repelled by
a magnet.
Sonorous
 An
object that produces a sound when
struck by another object.
Conductor
a
material that conducts or transmits
heat, electricity, or sound
Insulator
A substance that does not allow the heat or
sound to pass through
Semiconductor
A
substance that can conduct electricity
or heat under some conditions but not
others
Density Formula
D
= mass/volume
(I
density)
Water Displacement
A
method used to calculate
the volume of an irregular
shaped object.
Volume Formula
V
=LxWxH
