===Names and etymology===
In the 19th century, [[Jons Jacob Berzelius]] suggested calling the elements in group 16 "amphigens",<ref name="che.uc">{{cite journal|url=http://www.che.uc.edu/jensen/W.%20B.%20Jensen/Reprints/072.%20Chalcogen.pdf|title=A Note on the Term "Chalcogen"|doi=10.1021/ed074p1063|year=1997|author1-link=William B.

The term received some use in the early 1800s but is now obsolete.<ref name="che.uc"/> The name ''chalcogen'' comes from the Greek words ''{{lang|grc|χαλκος}}'' ({{lang|grc-Latn|chalkos}}, literally "[[copper]]"), and ''{{lang|grc|γενές}}'' ({{lang|grc-Latn|genes}}, born,<ref>{{cite web |last=Harper|first=Douglas|title=Online Etymology Dictionary|url=http://www.etymonline.com/index.php?term=-gen |access-date=November 25, 2013}}</ref> gender, kindle). It was first used in 1932 by [[Wilhelm Biltz]]'s group at [[Leibniz University Hannover]], where it was proposed by [[Werner Fischer (chemist)|Werner Fischer]].<ref name="chalcogen2">{{cite journal|author=Fischer, Werner|title=A Second Note on the Term "Chalcogen"|journal=Journal of Chemical Education|year=2001|volume=78|issue=10|page=1333|doi=10.1021/ed078p1333.1|bibcode = 2001JChEd..78.1333F |doi-access=}}</ref> The word "chalcogen" gained popularity in Germany during the 1930s because the term was analogous to "halogen".<ref>{{cite book|author=Krebs, Robert E. |title=The History And Use of Our Earth's Chemical Elements: A Reference Guide |url=https://books.google.com/books?id=yb9xTj72vNAC&pg=PA223 |year=2006 |publisher=Greenwood Publishing Group |isbn=978-0-313-33438-2 |pages=223– |access-date=November 25, 2013}}</ref> Although the literal meanings of the modern Greek words imply that ''chalcogen'' means "copper-former", this is misleading because the chalcogens have nothing to do with copper in particular. "Ore-former" has been suggested as a better translation,<ref name="chalcogen">{{cite journal|author=Jensen, William B.|journal=Journal of Chemical Education|year=1997|volume=74|issue=9|page=1063|doi=10.1021/ed074p1063|title=A Note on the Term "Chalcogen"|bibcode = 1997JChEd..74.1063J}}</ref> as the vast majority of metal ores are chalcogenides and the word ''{{lang|grc|χαλκος}}'' in ancient Greek was associated with metals and metal-bearing rock in general; copper, and its alloy [[bronze]], was one of the first metals to be used by humans.

Oxygen's name comes from the Greek words ''oxy genes'', meaning "acid-forming". Sulfur's name comes from either the Latin word ''{{lang|la|sulfurium}}'' or the [[Sanskrit]] word ''{{lang|sa-Latn|sulvere}}''; both of those terms are ancient words for sulfur. Selenium is named after the Greek goddess of the moon, [[Selene]], to match the previously discovered element tellurium, whose name comes from the Latin word ''{{lang|la|telus}}'', meaning earth. Polonium is named after Marie Curie's country of birth, Poland.<ref name="The Elements"/> Livermorium is named for the [[Lawrence Livermore National Laboratory]].<ref>{{cite web|last = Stark|first = Anne M|url = https://www.llnl.gov/news/newsreleases/2012/May/NR-12-05-07.html|title = Livermorium and Flerovium join the periodic table of elements|date = May 2012|access-date = November 25, 2013|archive-date = February 19, 2013|archive-url = https://web.archive.org/web/20130219040850/https://www.llnl.gov/news/newsreleases/2012/May/NR-12-05-07.html|url-status = dead}}</ref>
