/nɪˈhoʊ.ni.əm/ · noun
The synthetic transactinide chemical element with atomic number 113..
Japanese scientists behind the discovery of element 113, the first atomic element found in Asia - indeed, the first found outside Europe or the United States - have dubbed it "nihonium" after the Japanese-language name for their country.
In January 2016 the International Union of Pure and Applied Chemistry (IUPAC) announced the discovery of four new elements, so completing the seventh row of the periodic table. They have since been named as nihonium, Nh, muscovium^([sic]), Mc, tennessine, Ts, and organesson^([sic]), Og. The procedures for naming new elements are clearly laid out by IUPAC.
Researchers carefully choose the makeup of the beam and the target in hopes of producing a designer atom of the element desired. That’s how the four newest elements were created: nihonium (element 113), moscovium (115), tennessine (117) and oganesson (118) (SN Online: 11/30/16).
Use nihonium when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
Nihonium means The synthetic transactinide chemical element with atomic number 113..
Common synonyms include Nh, ununtrium, Uut, eka-thallium.
The opposite depends on the specific sense.
