[7] [8] When element 114 was synthesised in 1998 at Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, scientists at Livermore helped to confirm their discovery by assisting with independent analysis of their data. Stoyer generated a search code to search through the experimental data for decay ...
The discoveries of the 118 chemical elements known to exist as of 2025 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined.
This list of chemical elements named after people includes elements named for people both directly and indirectly. Of the 118 elements, 19 are connected with the names of 20 people. 15 elements were named to honor 16 scientists (as curium honours both Marie and Pierre Curie). Four others have indirect connection to the names of non-scientists. [1]
Dawn Angela Shaughnessy is an American radiochemist and principal investigator of the heavy element group at the Lawrence Livermore National Laboratory. [3] She was involved in the discovery of five superheavy elements with atomic numbers 114 to 118. [2]
The scientists involved in the discovery of element 118, as well as those of 117 and 115, held a conference call on 23 March 2016 to decide their names. Element 118 was the last to be decided upon; after Oganessian was asked to leave the call, the remaining scientists unanimously decided to have the element "oganesson" after him.
From 1932-1933, while at the University of Kansas, Weeks wrote a series of 21 articles on the discovery of the elements for the Journal of Chemical Education. [1] [2] Due to demand for reprints, the articles were collected and published in book form in 1933. [8] Discovery of the Elements went through multiple editions.

Her prize in chemistry was for her "discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element." Irene Joliot-Curie, Marie's daughter, became the second woman to be awarded this prize in 1935 for her discovery of artificial radioactivity.
