METALS
What are Metals?
Metals are elements which have the following
Physical Properties

• Shininess
• Malleability - Can be pounded into shapes
• Hardness
• Ductility - Can be pulled out into a wire ( ex
  coat hanger)
• Conductivity - transmit heat electricity easily

2
- Metals also have Chemical Properties

• Some metals are very reactive (they combine
  easily with other elements)

• Group 1 metals are the most reactive and if they
  are exposed to air or water can explode.
• Other metals such as gold are unreactive.

NONMETALS
What are Nonmetals?
- In general the Physical Properties of nonmetals
are opposite to those of metals

• Nonmetals have the following Physical Properties
• Most nonmetals are gases ( O, He, H, N)
• Most nonmetals are dull ( not shiny)
• Not malleable (brittle) or ductile
• Poor conductors of heat electricity

Nonmetals also have chemical properties
- Most nonmetals (except Noble Gases He,Ne,
Ar,Kr,Xe,Rn) readily form compounds with other
elements.
