Researchers in Sweden have confirmed a short-lived but super-heavy element dubbed ununpentium as its unofficial name.
BERLIN — Scientists in Sweden say they have confirmed the existence of a new chemical element, but its name may need some work.
Researchers at Lund University said Tuesday their find backs up claims by teams in Russia and the United States a decade ago that had remained unverified until now.
The Swedish scientists say they conducted experiments allowing them to detect the "fingerprint" of the short-lived but super-heavy element that's been dubbed ununpentium.
The name, which refers to the element's 115th place in the periodic table, is only provisional.
The element will likely get a new name if the discovery is formally approved by experts from the International Union of Pure and Applied Physics and Chemistry.
Well-known chemical elements include carbon, silicon and iron.
