List of chemical element naming controversies
open-in-new
<p>The currently accepted names and symbols of the <a href="/facts/Chemical_element/0jducgWD">chemical elements</a> are determined by the <a href="/facts/International_Union_of_Pure_and_Applied_Chemistry/2AV6myCK">International Union of Pure and Applied Chemistry</a> (IUPAC), usually following recommendations by the recognized discoverers of each element. However, the names of several elements have been the subject of controversies until IUPAC established an official name. In most cases, the controversy was due to a priority dispute as to who first found conclusive evidence for the existence of an element, or as to what evidence was in fact conclusive. </p>
