Alkali Metals

  • they are in group 1
  • really reactive
  • soft solids at room temperature
  • low melting and boiling points (this decreases as it goes down the group)
  • low densities - so lithium, sodium and potassium float on water
  • they all react with air and water (reaction with water produces hydrogen gas and a metal hydroxide that is a strong alkali)
  • they all have one electron in their outer shell, and lose this electron in reactions to form
