The priority of scientists now is to find the 'island of stability,' housing variants of an element that could last long enough to study, and could give rise to new technologies. The island is predicted to be located around element 114.

Nihonium, moscovium, tennessine and oganesson are the newest elements to receive names

The elements were recognized by the International Union of Pure and Applied Chemistry in December

CNN  — 

Meet nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og), the newest elements on the periodic table to receive names. But don’t get too attached to the nomenclature for these elements, formerly known by their respective atomic numbers 113, 115, 117 and 118. The names are on a five-month probation before things are made official.

The elements were recognized by the International Union of Pure and Applied Chemistry, or IUPAC, the U.S.-based world authority on chemistry, on December 30, 2015. Their addition completed the seventh row of the periodic table.

Kosuke Morita, the leader of the Riken team, smiles as he points to a board displaying the new atomic element 113 during a press conference in Wako, Saitama prefecture on December 31, 2015. A Japanese research team has received naming rights for new atomic element 113, the first on the periodic chart to be named by Asian scientists, the team's institute said December 31. Japan's Riken Institute said a team led by Kosuke Morita was awarded the rights from global scientific bodies -- the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP) -- after successfully creating the new synthetic element three times from 2004 to 2012.

Four new elements to be added to periodic table

The discoverers of the elements were invited to propose the names, and now a public review of the names begins, expiring on November 8, 2016. If you feel strongly about these names, the union invites you to provide comments and feedback here.

IUPAC provided the discoverers with guidelines to assist them in creating the names. These names keep with the longstanding tradition of being named after a mythological concept or character (including an astronomical object), a mineral or similar substance, a place or geographical region, a property of the element or a scientist.

And of course, they must end in “-ium,” “-ine,” or “-on” depending on the grouping of elements they belong to. IUPAC also prefers the names translate easily across major languages.

Other researchers are already hard at work searching for elements that will fill out the eighth row, as well as working to consolidate how copernicum and heavier elements are identified, according to IUPAC.

How the names came to be

All four elements are not found in nature, and were synthetically created in laboratories. Until now, these elements had temporary names and symbols on the periodic table as their existence was hard to prove. Because they decay extremely quickly, scientists found it difficult to reproduce them.

Element 113 is the first to be discovered in an Asian country. The researchers proposed the name nihonium to celebrate it. “Nihon” is one of two ways to say “Japan” in Japanese, and means “Land of Rising Sun.” The element was discovered by a team at RIKEN Nishina Center for Accelerator-Based Science and led by professor Kosuke Morita.

The researchers said their search for element 113 began by “bombarding a thin layer of bismuth with zinc ions traveling at about 10% the speed of light.” By doing so, they would theoretically fuse, forming an atom of element 113.

A Russian-American team at the Joint Institute for Nuclear Research in Dubna, Russia, and at Oak Ridge National Laboratory in Tennessee and Lawrence Livermore National Laboratory in California discovered elements 115, 117 and 118.

Both moscovium and tennessine honor where they were discovered: Moscow and Tennessee, respectively. Researchers used the Dubna Gas-Filled Recoil Separator at the Joint Institute for Nuclear Research along with the heavy ion accelerator capabilities at the Flerov Laboratory of Nuclear Reactions in Moscow. For tennessine, researchers at the Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee at Knoxville worked together on superheavy element research and synthesis using Oak Ridge’s High Flux Isotope Reactor and Radiochemical Engineering Development Center.

    Oganesson, discovered by collaborating teams at the Russian Joint Institute for Nuclear Research and U.S.-based Lawrence Livermore National Laboratory, was named for professor Yuri Oganessian. The scientist, born in 1933, was a pioneer with achievements including the discovery of superheavy elements.

    Jan Reedijk, president of IUPAC’s inorganic chemistry division, said it’s a pleasure to see people and places recognized in the four elements.

    “Although these choices may perhaps be viewed by some as slightly self-indulgent, the names are completely in accordance with IUPAC rules,” a statement from Reedijk said. “In fact, I see it as thrilling to recognize that international collaborations were at the core of these discoveries and that these new names also make the discoveries somewhat tangible.”
