    The lanthanide ( ˈ l æ n θ ə n aɪ d ) or lanthanoid ( ˈ l æ n θ ə n ɔɪ d ) series of chemical elements [a] comprises at least the 14 metallic chemical elements with atomic numbers 57–70, from lanthanum through ytterbium In the periodic table, they fill the 4f orbitals
  • 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 Facts (Lanthanoids) Recently updated - Science Notes and . . .
    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

  • What Are Lanthanides? - BYJUS
    Lanthanides are the rare earth elements of the modern periodic table, i e , the elements with atomic numbers from 58 to 71, following the element lanthanum They are called rare earth metals since the occurrence of these elements is very small (3×10 -4 % of the Earth’s crust) They are available in ‘monazite’ sand’ as lanthanide orthophosphates

    The lanthanides (which, along with the actinides, are sometimes referred to as rare earth metals) is a special group of metallic elements, usually shown in the periodic table as the first row in a separate block, underneath the transition metals
  • Lanthanides - Definition, Configuration, Properties
    Lanthanides are the contemporary periodic table's rare earth elements, with atomic numbers ranging from 58 to 71 after Lanthanum Rare earth metals are so-called because these elements are extremely rare (3 × 10 -4 % of the Earth's crust) As lanthanide orthophosphates, they are accessible in 'monazite' sand
