  • Lanthanide - Wikipedia
    The lanthanide contraction is responsible for the great geochemical divide that splits the lanthanides into light and heavy-lanthanide enriched minerals, the latter being almost inevitably associated with and dominated by yttrium
  • Lanthanides Facts (Lanthanoids) - Science Notes and Projects
    Chemists refer to these 15 elements using the symbol Ln They are called “lanthanides” because they share properties in common with lanthanum Here is a list of the lanthanides, a look at their common properties, their uses, and other facts
  • Lanthanide | Definition, Start, Facts | Britannica
    Lanthanide, any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57–71) With scandium and yttrium, they make up the rare-earth metals
  • Lanthanides: Properties and Reactions - Chemistry LibreTexts
    The Lanthanide Contraction refers to the decrease in atomic size of the elements in which electrons fill the f-subshell Since the f sub-shell is not shielded, the atomic size will decrease as the nuclear charge still increases
