1. METALS
Metals are… Solid at room temperature, except mercury, which is liquid !
Metals have… very high melting and boiling point.
Metals are… Lustrous when they cut.
Metals are… good conductors of heat and electricity.
Metals are… usually strong & malleable so they can be hammered into shape.
Metals are… ductile and can be pulled into a wire

2. NON - METALS
Non-Metals are… Solid, or Gas at room temperature, except bromine, which is liquid !
Non- Metals have… Low melting and boiling point.
Non- Metals are… Dull.
Non- Metals are… Poor conductors of heat and electricity.
Non- Metals are… Brittle and not malleable so they can not be hammered into shape.
Non- Metals are… Not ductile

4. METALLOIDS Have properties of both metals and non-metals.
Example: Silicon
Like a Metal because…
* Lustrous, hard, silver
Like a Non-metal because…
non-malleable, non- ductile, poor conductor of electricity

10. DISADVANTAGES OF MERCURY
Mercury is a bioaccumulative toxin that is easily absorbed through the skin, respiratory and gastrointestinal tissues.
Mercury attacks the central nervous system and adversely affects the mouth, gums, and teeth.
High exposure over long periods of time will result in liver and brain damage and ultimately death. It can pose a major health risk to the unborn fetus.

11. Other Uses Of MERCURY
Teeth Filings - inserted into the tooth and the amalgam expanded as it dried to fill the entire cavity
Top Hats – Line the brim to prevent it from blowing away
Fluorescent Light Bulbs

12. LEAD IS POISONOUS TOO! USE TO BE FOUND IN: Pencils Glassware
Gasoline Body Filler in Cars
Paint Food Containers
Lead is a poisonous metal that can damage nervous connections (especially in young children) and cause blood and brain disorders.
Exposure to high lead levels can severely damage the brain and kidneys in adults or children and ultimately cause death.
In pregnant women, high levels of exposure to lead may cause miscarriage.
