Source-derived summary

Flerovium is a synthetic chemical element; it has symbol Fl and atomic number 114. It is an extremely radioactive, superheavy element, named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1999. The lab's name, in turn, honours Russian physicist Georgy Flyorov. IUPAC adopted the name on 30 May 2012. The name and symbol had previously been proposed for element 102 (nobelium) but were not accepted by IUPAC at that time.

Editorial summary

“Flerovium” enters the record as chemical element with atomic number 114 (Fl). Crown Archives preserves that source wording while asking what Flerovium, Chemical and element can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1999, 2012—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Flerovium, Chemical and element.
Editorial analysis

Why this record matters

“Flerovium” is worth following because a concise public description often conceals a longer documentary argument. Here, Flerovium, Chemical and element provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 23, 2026. The first chronological checks are 1999 and 2012.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
