- ALKALI METALS
- LITHIUM (Li)
- least reactive alkali metal
- when mixed with water lithium fizzes gently and a few bubbles
- SODIUM (Na)
- when mixed with water sodium fizzes quicker and creates smoke and made a loud bubbling noise
- POTASSIUM (K)
- when mixed with water potassium very vigorously fizzes and creates a blue-purple flame and a loud fizzing
- CAESIUM (Cs)
- when caesium is mixed with water it is a bigger explosion than rubidium
- RUBIDIUM (Rb)
- when rubidium is mixed with water rubidium explodes and shatters the container
- FRANCIUM (Fr)
- the most reactive alkali metal
- Trends in group 1 - alkali metals
- reactivity increases down group 1
- all alkali metals have to be stored in oil as the react with oxygen
- alkali metals are soft enough to cut with a knife
- as the elements get more reactive the melting point decreases
- LITHIUM (Li)
