We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Terbium — [contradicted] Originally, 'erbia' was the fraction containing the pink color due to what is now known as erbium, while 'terbia' contained what is now known as terbium. :: Source explicitly states: 'Terbia was originally the fraction that contained the pink co
Vanadium — [contradicted] He initially thought it was a new element, but French chemist Hippolyte Victor Collet-Descotils erroneously convinced him it was chromium. :: The source states that del Río initially presumed its qualities were due to a new element, was erroneou
Ytterbium — [contradicted] Ytterbium is named after the village of Ytterby in Sweden, which also gave names to yttrium, terbium, and erbium. :: The source states that four elements were named after the village: yttrium, terbium, erbium, and ytterbium (ytterbium is itself
Tantalum — [contradicted] These make it indispensable for reaction vessels, vacuum furnaces, and tantalum capacitors in computers and other electronics. :: flagged by an independent model family (deepseek-v4-flash) against the source article; the same-family audit missed
Tantalum — [contradicted] Historically, the confusion between tantalum and niobium, resolved over decades by multiple chemists, illustrates the challenges of early analytical chemistry. :: flagged by an independent model family (deepseek-v4-flash) against the source arti
