Very Rare / HistoricalTechnical / Historical Scientific
Definition
Meaning
A disused, historical name for the chemical element Ytterbium (symbol Yb, atomic number 70).
A term found primarily in older scientific literature referring to one of the lanthanide series rare-earth elements, initially distinguished from 'ytterbium' before they were recognized as the same element.
Linguistics
Semantic Notes
This term is obsolete. It was used in the early 20th century during the period of confusion and discovery surrounding the rare-earth elements. Modern usage exclusively employs 'ytterbium'. 'Neoytterbium' is encountered only in historical texts or discussions of the history of chemistry.
Dialectal Variation
British vs American Usage
Differences
No significant regional differences exist, as the term is obsolete globally. Both UK and US scientific communities abandoned it in favour of 'ytterbium'.
Connotations
Historical, archaic, of interest primarily to historians of science.

Examples
By CEFR Level
- Ytterbium is a metal. Long ago, some scientists called it 'neoytterbium'.
- In his 1907 paper, the chemist referred to the purified sample as neoytterbium, a term later superseded.
- The convoluted history of the rare-earth elements includes the temporary designation 'neoytterbium' for what we now uniformly classify as ytterbium.
Learning
Memory Aids
Mnemonic
Think 'NEW-Ytterbium' (neo = new). It was the 'new' or refined understanding of the element ytterbium, though the name didn't stick.
Conceptual Metaphor
A NAME DISCARDED ON THE PATH TO TRUTH (The history of science involves discarding provisional names for final, accurate ones).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with modern Russian 'иттербий' (ytterbium). 'Neoytterbium' would be a direct transliteration 'неоиттербий', which is not a standard modern term.
Common Mistakes
- Using 'neoytterbium' in a modern scientific context.
- Spelling it as 'neo-ytterbium' or 'neo ytterbium'.
- Assuming it is a different element from ytterbium.

FAQ
Frequently Asked Questions
No. 'Neoytterbium' is an obsolete name for the same element, ytterbium (Yb).
No. It is a historical term. Always use 'ytterbium' in modern scientific, academic, or general contexts.
Early chemists struggled to separate and identify the very similar rare-earth elements. 'Neoytterbium' and 'ytterbium' originally referred to slightly different materials or purities that were later proven to be the same element.
Exclusively in historical scientific literature, particularly from the period 1900-1920, or in modern texts about the history of chemistry.
