The Alkali Metals:
- The elements in group 1 of the periodic table are called alkali metals.
- The Metals all react with hydrogen and Alkaline solution containing the metal hydroxide
- The reactivity of the alkali metals increases as we go down the group.
- Lithium at the top of the group is less reactive than Caesium, near the bottom of the group. These elements always form Alkaine compounds.
A balanced Equation for the reaction of Caesium with iodine:
Caesium + Iodine…
