1. Fold you paper hot-dog way2. Fold into 3
squares3. Cut only the top creases to make 3
windows4. Write Metals, Non-Metals and
Metalloids on the 3 flaps5. Use the info on the
following slides to write into your foldable6.
Always put the Physical Properties info on the
top part of the flap and the Chemical Properties
info on the bottom part of the flap.7. Write
your name on the back and give to teacher.

METALS
Physical Properties (Substance does not change)
Chemical Properties (Forms a new substance)

• Very Reactive
• (lose electron)
• Corrode easily (iron
• rusts silver tarnishes)

• Luster (shiny)
• Conduct Electricity/Heat
• State of Matter
• (Solid _at_ room Temp)
• High Melting Point
• High Density
• Malleable/Ductile

9
NON-METALS
Physical Properties (Substance does not change)
Chemical Properties (Forms a new substance)

• No Luster (dull)
• Poor Conduct (Insulates)
• State of Matter
• (Gas _at_ room Temp)
• Low Melting Point
• Low Density
• Brittle

• Very Reactive
• (gain electron -
• from Group 1)
• Very stable

10
METALLOIDS
Physical Properties (Substance does not change)
Chemical Properties (Forms a new substance)

• Properties of both metals
• non-metals

• Properties of both metals
• non-metals
• Often make good semiconductors

Zig-Zag / Stair Steps

Periodic Table of Elements

• Position of element predicts physical chemical
  properties
• Organized by Atomic
• Group/ Family
• Column (1-18) or (I-VIII)
• Share physical chemical properties
• Period
• Row
• Increase by 1 atomic number from left to right
