Alkali metals:

  • Chemical elements like lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr) are alkali metals.
  • All alkali metals have their outermost electron in an s-orbital.
  • The alkali metals are shiny, soft, and highly reactive metals.
  • Alkali metals have high reactivity therefore they must be stored under oil to prevent reaction with air.
  • All the alkali metals react with water.
  • The heavier alkali metals react more vigorously than the lighter ones.
