    1. Block
    14 elements
  • Electron Configuration
    Matches the 14 elements in the f-block
  • All actinides are radioactive, with the radioactivity increasing with higher atomic numbers (e.g. uranium, plutonium)
  • Actinides have no stable isotopes
  • Lanthanides often form colorful ions, causing them to be used in various color applications (e.g. gadolinium)
