Groups:
1. Trend of Radius/I.E./E.N.
2. Reaction with water/oxygen/chlorine
3. Decomposition of nitrate and carbonate of Group II
4. Trend of solubility of Group II
The periodic properties of the elements results from the trend of the atomic or ionic properties.

Periodicity for Period
Periods:
1. Trend of Radius/I.E./E.A./E.N.
2. Metal and Non-metal (Transferring / Sharing Electrons)
3. Oxide and Chloride (Structure and Physical Properties)
4. Reaction of Oxide and Chloride with water/acid/base
It is a great practice to connect the physical and chemical properties in a series.
