List of misidentified chemical elements

Chemical elements that have been mistakenly "discovered". Further investigation showed that their discovery was either mistaken, that they have been mistaken from an already-known element, or mixture of two elements, or that they indicated a failing in theory where a new element had been assumed rather than some previously unknown behaviour.

Ausonium

Ausonium was the name assigned to the element with atomic number 93, now known as neptunium. It was named after a Greek name of Italy, Ausonia. The same team assigned the name hesperium to element 94, after Hesperia, a poetic name of Italy. Element 94 was later named plutonium. The discovery of the element, now discredited, was made by Enrico Fermi and a team of scientists at the University of Rome in 1934. In the same year Ida Noddack had already presented alternative explanations for the experimental results of Fermi. Following the discovery of nuclear fission in 1938, it was realized th ...

Austrium

Austrium is the name of a new chemical element proposed by Eduard Linnemann in 1886. As a chemist at the German University in Prague he experimented with the mineral orthite. In the course of his works over several years he detected spectral lines at 4165 and 4030 Angstrom, respectively, which he was not able to ascribe to any then known element. These findings were published only after his death after due consideration on May 6, 1886 by the Academy of Sciences of Prague. Subsequently, the French chemist Paul Emile Lecoq de Boisbaudran pointed out that Linnemanns findings could also be att ...

Bohemium

Bohemium was the name assigned to the element with atomic number 93, now known as neptunium, when its discovery was first incorrectly alleged. It was named after Bohemia. The alleged discovery took place in 1934 and it was published shortly after Enrico Fermi claimed the discovery of element 93, which he called ausonium. Both discoveries were proven wrong after the discovery of nuclear fission in 1938. But even before that time the discovery was reviewed with a negative outcome. The alleged discovery of the element, now discredited, was made by Odolen Koblic, a Czech engineer.

Berzelium

Carolinium and berzelium were the proposed names for new chemical elements that Charles Baskerville believed he had isolated from the already known element thorium. During his time at the University of North Carolina, Baskerville experimented with thorium and published his results in 1901. He reported having separated thorium into three fractions with slightly different chemical properties: the known thorium and two new elements, carolinium symbol Cn and berzelium symbol Bz. The names derived from two sources: the other element was named after Jons Jakob Berzelius, a renowned Swedish chemi ...

Newtonium

Coronium, also called newtonium, was the name of a suggested chemical element, hypothesised in the 19th century. The name, inspired by the solar corona, was given by A. Gruenwald in 1887. A new atomic thin green line in the solar corona was then considered to be emitted by a new element unlike anything else seen under laboratory conditions. Because of this it was also mis-classified as Iron Line Number 1474.
