Alkali metals
- Group 1
- Soft
- Shiny when cut(reacts
with air to go dull)
- Reactions with Oxygen
- lithium + oxygen ---> lithium oxide
- 4Li + O2 -----> 2Li2O
- Need to be stored in oil
- Reactions become
progressively more violent
down the group
- Reactions with water
- Alkali metals react more violent with water
- lithium + water ---> lithium hydroxide + hydrogen
- 2Li + 2H2O ----> 2LiOH + H2
- Reactions get progressively more violent down the group
- Potassium creates heat as it reacts with water to
produce hydrogen that then gets lit to produce a
lilac flame
- Reactions with halogens
- lithium + chlorine ----> lithium chloride
- 2Li + Cl2 ---> 2LiCl
- Reactions become
progressively more violent
down the group
- lithium reacts with chlorine gas
to produce the salt lithium
chloride
