    metals.
  • The metals are very shiny, but tarnish in air.
  • The metals have high ability to conduct with
    electricity.

5
Chemical Properties
  • Very reactive.
  • Tarnish when exposed to air, forming their
    oxides.
  • High melting points and boiling points.
  • Reacts with water
  • Burns easily in air.
  • Reacts with ultraviolet light.

6
Uses
  • Petroleum products.
  • Lanthanides are used in lamps, lasers, magnets,
