1. CHEMICAL PERIODICITY

2. Group Trends Transition Metals Innertransition Metals
Main Block Elements
Hydrogen
Alkali Metals
Alkaline Earth Metals
Halogens
Noble Gases

3. Transition & Innertransition Metals
Valence electrons found on more than one energy level
Ductile, malleable, and conducts electricity
Lanthanoids
Actinoids

4. Main Block Elements Hydrogen
Most abundant element in the universe
Colorless gas
Dangerous due to its flammability (used to be used in hot air balloons)

5. Main Block Elements Alkali Metals
Most reactive metals
Found in Group 1
One valence electron
Softer than other metals
Malleable, ductile, and good conductors
Explode in cold water

6. Main Block Elements Alkaline Earth Metals
Reactive metallic elements
Found in Group 2
Two valence electrons
Not found free in nature

7. Main Block Elements Halogens
Very reactive non-metallic elements
Found in Group 17
Seven valence electrons
Group has all 3 states of matter

8. Main Block Elements Noble Gases
Unreactive gases
Found in Group 18
Eight valence electrons
Very stable
