Usage notes
* According to IUPAC - "Although lanthanoid means 'like lanthanum' and so should not include lanthanum, lanthanum has become included by common usage. Similarly, actinoid. The ending 'ide' normally indicates a negative ion, and therefore lanthanoid and actinoid are preferred to lanthanide and actinide. However, lanthanide and actinide are still allowed owing to wide current use."
Synonyms
* lanthanate (obsolete)
* lanthanoid (including lanthanum )
* lanthanon (proposed to avoid confusion with the usual meaning in chemistry of -ide )
* rare-earth element
