2. Periodic Table Families and Properties

4. Properties of Metals
Malleable-  able to be hammered or pressed permanently out of shape without breaking or cracking
Ductile- able to be drawn out into a thin wire
Luster- “to shine”
Excellent conductor of heat and electricity
Most elements on the periodic table are metals

5. Properties of Non-Metals
Are NOT good conductors of heat or electricity
Brittle
Little or no metallic luster

6. Properties of Metalloids
Share properties of both metals and non-metals
Semi-conductors= insulate and conduct electricity
Very useful for technological equipment, such as computer chips

7. Families of the Periodic Table

8. Families of the Periodic Table
Group 1- Alkali Metals (1 valence electron)
Most reactive metal family; explode when mixed with water
Group 2- Alkaline Earth Metals (2 valence electrons)
Reactive metals but not as reactive as Alkali
Groups Transition Metals
Gold, silver, iron, and copper are examples, just to name a few
Group 17- Halogens (7 valence electrons)
“salt formers”
Group 18- Noble Gases
Virtually non-reactive due to full outer/valence shell
