Period 2
- Reactions with water
- Beryllium has no reaction with water or steam even at red heat.
- Magnesium burns in steam to produce white magnesium oxide and hydrogen gas.
- These all react with cold water with increasing vigour to give the metal hydroxide and hydrogen.
Strontium and barium have reactivities similar to lithium in Group 1 of the Periodic Table.
- Beryllium has a strong resistant layer of oxide on its surface which lowers its reactivity.
