Ausenium and hesperium is a topic that arouses interest and debate in different areas of society, from politics to popular culture. Throughout the article, we will examine the many facets of Ausenium and hesperium, analyzing its impact on people's daily lives and its relevance in the global picture. In addition, we will delve into its history, evolution and possible future developments, in order to offer a complete and updated vision of Ausenium and hesperium. From its origins to its future implications, this article aims to shed light on a topic that continues to capture the attention of individuals with different profiles and interests.
Ausenium (atomic symbol Ao) and Hesperium (atomic symbol Es) were the names initially assigned to the transuranic elements with atomic numbers 93 and 94, respectively. The discovery of the elements, now discredited, was made by Enrico Fermi and a team of scientists at the University of Rome in 1934.
Following the discovery of nuclear fission in 1938, it was realized that "elements" found by Fermi were actually a mixture of barium, krypton, and other elements. The actual elements were discovered several years later, and assigned the names neptunium and plutonium.[1] Already in 1934, Ida Noddack had presented alternative explanations for the experimental results of Fermi.[2]
The element 93, ausenium, was named after a Greek name of Italy, Ausonia.[3] The element 94, Hesperium, was named in Italian Esperio after Hesperia, a poetic name of Italy.[1]
Fascist authorities wanted one of the elements to be named littorio after the Roman lictores who carried the fasces, a symbol appropriated by Fascism.[1]
