'''Superheavy elements''', (also known as ''superheavies'', or ''superheavy atoms'', commonly abbreviated '''SHE''') usually refer to the transactinide elements beginning with [[rutherfordium]] (atomic number 104). (Lawrencium, the first 6d element, is sometimes but not always included as well.) They have only been made artificially and currently serve no practical purpose because their short half-lives cause them to decay after a very short time, ranging from a few hours to just milliseconds, which also makes them extremely hard to study.<ref name="She">{{cite journal|last1=Heenen|first1=Paul-Henri|last2=Nazarewicz|first2=Witold|author-link2=Witold Nazarewicz|year=2002|title=Quest for superheavy nuclei|url=https://www.europhysicsnews.org/articles/epn/pdf/2002/01/epn02102.pdf|url-status=live|journal=Europhysics News|volume=33|issue=1|pages=5–9|bibcode=2002ENews..33....5H|doi=10.1051/epn:2002102|archive-url=https://web.archive.org/web/20180720100024/https://www.europhysicsnews.org/articles/epn/pdf/2002/01/epn02102.pdf|archive-date=20 July 2018|doi-access=free}}</ref><ref name="Green">{{cite journal|last1=Greenwood|first1=Norman N.|year=1997|title=Recent developments concerning the discovery of elements 100–111|url=https://old.iupac.org/publications/pac/1997/pdf/6901x0179.pdf|url-status=live|journal=[[Pure and Applied Chemistry]]|volume=69|issue=1|pages=179–184|doi=10.1351/pac199769010179|s2cid=98322292|archive-url=https://web.archive.org/web/20180721170653/https://old.iupac.org/publications/pac/1997/pdf/6901x0179.pdf|archive-date=21 July 2018}}</ref>

Superheavies have all been created since the latter half of the 20th century and are continually being created during the 21st century as technology advances. They are created through the bombardment of elements in a particle accelerator, in quantities on the atomic scale, and no method of mass creation has been found.<ref name="She"/>
