![]() ![]() roentgenium (Rg, element 111, IUPAC placeholder name unununium), after German scientist Wilhelm Röntgen, who first detected X-rays.darmstadtium (Ds, element 110, IUPAC placeholder name ununnilium), after Darmstadt, Germany, near the lab where it was discovered.In 2011, the IUPAC approved the name of three elements according to its guidelines: What are the names of some of the most recently discovered chemical elements? A mythological concept or character (including an astronomical object).For these names, the IUPAC observes tradition and allows new elements to be named after: ![]() When it comes to new elements, the IUPAC invites discoverers to propose names, which it then considers and puts up for approval. In a 100-plus-paged manual, the IUPAC lays out it recommendations for the naming of chemical substances. They are sometimes toponyms, too, named for places (of discovery), as americium. Many of these elements, discovered in the 19th and 20th centuries, are eponyms, named in honor of important scientists, such as curium (for Marie Curie) or einsteinium (for Albert Einstein). They are very unstable and quickly dissolve into other elements. Unlike common elements, newer elements are synthesized in a lab they are not observed in nature. And, did you know cobalt comes from a German word meaning “evil spirit”?! Carbon comes from the Latin for “charcoal.” Helium comes from the Greek helios, “sun.” Iron is from a Germanic root for the heavy metal. Name choices were inspired by where the element is found or some other defining characteristic. The common elements like carbon, helium, and iron-many of which became chemically understood in the 1600–1800s-were named for common things by the scientists who described or discovered them, often on the basis Greek, Latin, or Germanic words. But, what about flerovium and livermorium? How did they get their names? How are chemical elements named? ![]() Ununhexium is a mouthful, if perhaps exotic- or futuristic-sounding. Hydrogen has one proton, gold 79, flerovium 114, to name a few. The periodic table of elements is organized around atomic numbers. These numbers correspond to their atomic numbers, or the number of protons in the nucleus of an atom. Until the discovery of these predicted elements occurred, they were known as ununquadium and ununhexium, which is scientific Latin for 114 and 116, respectively. With the chemical symbols of Fl and Lv, these names became official in 2012. In 2011, the International Union of Pure and Applied Chemistry (IUPAC) recognized the discovery of two new chemical elements: flerovium and livermorium. ![]()
