3. Properties of Common Groups
Alkali Metals (Group 1A or 1)
the most reactive metal family
must be stored under oil
react with water violently!
Alkaline Earth Metals (Group 2A or 2)
except for Be(OH)2, the metal hydroxides formed by this group create basic (pH > 7) solutions in water
pastes of these used in batteries

4. Properties of Common Groups
Chalcogen family (Group 6A or 16)
many found combined with metal ores
Halogens (Group 7A or 17)
known as the “salt-formers” because they form ionic compounds with metals
used in modern lighting

5. Properties of Common Groups
Noble gases (Group 8A or 18)
known for their disinterest in other elements
once thought to never react
neon used to make bright RED signs
Transition Metals (Group 8A or 18)
