Group 1 Metal | Periodic table

1. The Alkali Metals form Group I of The Periodic Table, and called so because they form oxides and hydroxides that dissolve in water to give alkaline solutions. 2. They form the first element of a period, with one outer electron. This outer electron similarity makes them behave in a chemically similar way 3. They are so reactive that they must be stored under oil to minimise reaction with oxygen or water vapour in air.
