 (lăn′thə-nīd′)
n.
Any of a series of chemically similar metallic elements with atomic numbers ranging from 57 (lanthanum) through 71 (lutetium). The lanthanides, together with yttrium and scandium, constitute the rare-earth elements. Also called lanthanoid.

lan·tha·nide

(lăn′thə-nīd′)
Any of a series of 15 naturally occurring metallic elements. The lanthanides include elements having atomic numbers 57 through 71. They are grouped apart from the rest of the elements in the Periodic Table because they all behave in a similar way in chemical reactions. Also called rare-earth element. See Periodic Table.

In Periods 6 and 7, within the numbers 58-71 and 90-103, families of Lanthanoids and Actinides are located, respectively.
through protocorm-like bodies: effects of plant growth regulators and lanthanoids.
The synergistic extraction of trivalent actinoids and lanthanoids is of great interest because of the high extraction efficiency of these metal ions in the presence of a chelating agent and a neutral donor [1-7].
Changes in this edition include updates to the chapters on organometallic catalysis in synthesis and production, bioorganometallic chemistry, and new developments in the field; there is also a new chapter on organometallic chemistry of the lanthanoids and actinoids.
The next pair of presentations looked at some of the relationships other than groups and periods, such as the diagonal relationship, the (n) and (n+ 10) relationship, the Knight's move relationship, isoelectronic patterns, relationships among the lanthanoids and actinoids, and the concepts of "combo" and pseudo elements.
