1. The Periodic Table GROUPS

2. ALKALI METALS very reactive metals
Hydrogen is not a member, it is a non-metal
1 electron in the outer shell
combine violently with water (stored in oil)
Only compounds in nature
soft and shiny (can be cut with a knife)

3. ALKaLINE EARTH METALS very reactive (less reactive than alkali metals)
-only compounds in nature
-hard, grey-white, good conductors
2 electrons in the outer shell

4. TRANSITION METALS
ductile and malleable, and conduct electricity and heat
groups 3-12
bridge between very reactive and less reactive elements

5. METALLOIDS
have properties of both metals and non-metals.
semiconductor/insulator of electricity

6. HALOGENS
exist in all three states of matter
-dangerous to humans
-poisonous and highly corrosive

7. NOBLE GASES
do not form compounds easily
found in the atmosphere
-chemically stable/not reactive
Happy Elements (Full outer shells)

8. RARE EARTH ELEMENTS Lanthanides & Actinides
