1 Metals, Nonmetals, and Metalloids (Vocabulary)

2 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.

3 Metals  Elements which have physical properties such as good conductivity, shiny luster, malleability and ductility.

4 Nonmetals  Elements which have physical properties such as no conductivity (an insulator), dull luster, and brittleness (will break).

5 Metalloids  Elements which can have both properties of metals and nonmetals.  Also may be called a semi- conductor.

6 Luster  The way a substance reflects light;  Examples  Shiney  Dull  Metalic  Waxy

7 Malleability  How well it can be hammered into thin sheets.  Examples  Flattened penny  Aluminum can  Tin foil  Aluminum foil

8 Brittle  The tendency to break, snap, or crack without first bending or changing shape as a result of application of little force.

9 Conductivity  How well it allows electricity to move through.

10 Ductility  Can be stretched into wire.

11 Magnetism  Attracted to or repelled by a magnet.

12 Conductor  a material that conducts or transmits heat, electricity, or sound

13 Insulator A substance that does not allow the heat or sound to pass through

14 Semiconductor  A substance that can conduct electricity or heat under some conditions but not others

15 Sonorous  An object that produces a sound when struck by another object.

16 Density Formula  D = mass/volume  (I density)

17 Water Displacement  A method used to calculate the volume of an irregular shaped object.

18 Volume Formula  V = L x W x H
