Unbihexium, also known as element 126 or eka-plutonium, is the hypothetical chemical element with atomic number 126 and placeholder symbol Ubh. Unbihexium and Ubh are the temporary IUPAC name and symbol, respectively, until the element is discovered, confirmed, and a permanent name is decided upon. In the periodic table, unbihexium is expected to be a g-block superactinide and the eighth element in the 8th period. Unbihexium has attracted attention among nuclear physicists, especially in early predictions targeting properties of superheavy elements, for 126 may be a magic number of protons near the center of an island of stability, leading to longer half-lives, especially for 310Ubh or 354Ubh which may also have magic numbers of neutrons.

  • L'Unbihexi és el nom temporal d'un element superpesant encara no sintetitzat, amb el símbol temporal Ubh i nombre atòmic 126. L'element, també conegut com a -plutoni o simplement element 126, es prediu que sigui a prop del centre d'una hipotetica illa d'estabilitat,i per tant pot tenir una vida mitjana llarga, força més gran que la que es podria predir sense l'illa d'estabilitat. A raó d'això, ha atret interès d'investigadors que han provat de sintetitzar-lo. (ca)
  • Το Ουνμπιέξιο είναι το προσωρινό του με ατομικό αριθμό 126 και προσωρινό χημικό σύμβολο Ubh. Τα ραδιοϊσότοπα του στοιχείου που έχουν τη μεγαλύτερη περίοδο ημιζωής είναι το 310Ubh και το 322Ubh. (el)
  • El unbihexio, o eka-plutonio es el nombre temporal de un elemento químico desconocido de la tabla periódica que tiene el símbolo temporal Ubh y número atómico Z=126.​ Los cálculos muestran que 332Ubp sería el segundo isótopo más estable. (es)
  • Unbiheksium (pengucapan: /ˌʌnbɪˈhɛksiəm/) adalah nama sementara unsur kimia yang belum ditemukan dalam sistem periodik unsur yang memiliki lambang Ubh dan nomor atom 126. (in)
  • 운비헥슘(Unbihexium)은 미발견된 원소의 임시 이름으로, 원소 기호는 Ubh, 원자 번호는 126번이다. 운비헥슘 310은 안정성의 섬에 들어 있어 긴 반감기를 가질 것으로 예측되고 있다. 운비헥슘 322도 긴 반감기를 가질 것으로 예측된다. 1971년 합성 실험을 시도하였으나 실패하였다. 이 실험을 수행하는 과정에서 높은 에너지의 α 입자가 방출되었는데, 당시에는 이것을 운비헥슘 합성의 증거로 간주하였으나 현재는 당시 사용한 장치의 감도로는 이와 같은 검출이 가능하지 않았을 것으로 간주해 합성이 이루어지지 않은 것으로 여긴다.

  • Unbihexium (Ubh, ang. unbihexium) – niezsyntetyzowany dotąd, hipotetyczny pierwiastek chemiczny o liczbie atomowej 126. Taka liczba protonów w jądrach tego pierwiastka może (według części modeli budowy jąder) zwiększać ich stabilność; przewiduje się, że ten pierwiastek znajduje się na hipotetycznej wyspie stabilności.

  • Unbihéxio, também chamado de Eka-plutônio ou simplesmente elemento 126, é um elemento químico hipotético com número atômico 126 e símbolo temporário Ubh. Unbihéxio e Ubh são o nome e o símbolo sistemáticos temporários da IUPAC, até que um nome permanente seja decidido. Na tabela periódica dos elementos, espera-se ser um elemento do novo bloco g, um metal de transição interna e o oitavo elemento no oitavo período da Tabela Periódica. (pt)
  • Unbihexium, eller grundämne 126 med den kemiska beteckningen Ubh, är det tillfälliga IUPAC-namnet. Det kan också kallas eka-plutonium efter Dmitrij Mendelejevs förutsägelser om det periodiska systemet. Unbihexium är det åttonde grundämnet i den åttonde perioden i det periodiska systemet. Det har inte gjorts några försök att framställa ämnet. (sv)
  • 126號元素(Unbihexium)是一種尚未被發現的化學元素,它的暫定化學符號是Ubh,原子序數是126,位於第8周期、g3族,屬於g區元素之一。雖然126号元素尚未被合成,但由于其处在假想的稳定元素岛中而引起兴趣。 (zh)
  • Unbihexium ist das bisher noch nicht nachgewiesenene chemische Element mit der Ordnungszahl 126.Im Periodensystem steht es zwischen dem 125Unbipentium und dem 127Unbiseptium. Der Name ist vorläufig und leitet sich von der Ordnungszahl ab. Bei dem Unbihexium-Isotop Ubh-310 wird eine im Vergleich zu benachbarten Nukliden überdurchschnittlich lange Halbwertszeit erwartet, weil nicht nur seine Protonenzahl 126, sondern auch seine Neutronenzahl 184 „magisch“ ist.
