1. Chemical Periodicity

2. Group II
The focus for Chemical Periodicity is the trends for the
physical and chemical properties of the elements
across Period 3.

3. Physical Properties
•
•
•
•
Atomic radii
Ionisation Energy (IE)
Melting point/ boiling point (mp/ bp)
Electrical conductivity
For each property, it is important to:
(1) remember the trends
(2) learn to explain for the trends

4. Physical Properties
1. Rxn with Oxygen
2. Rxn of Oxides with H2O
3. Rxn of Oxides with Acid/ Base
4. Reactions with Chlorine
5. Rxn of Chlorides with Water
