  • IUPAC awarded credit for the discovery of element 113 to a team of scientists from the Riken institute in Japan. Kosuke Morita, who was leading the research at Riken, said his team now planned to “look to the unchartered territory of element 119 and beyond.

    日前,日本理化学研究所的科学团队因发现113号元素而受到国际纯粹与应用化学联合会嘉奖。Kosuke Morita于日本理化研究所负责该研究,他说自己的团队还计划探索119号元素尚未开垦的领域以及其他领域。

    Ryoji Noyori, former Riken president and Nobel laureate in chemistry said: “To scientists, this is of greater value than an Olympic gold medal”.

    日本理化学研究所前所长、诺贝尔化学奖获得者Ryoji Noyori说:“对科学家而言,这一成就比奥运会金牌还要有价值的多。”

    The elements, which currently bear placeholder names, will be officially named by the teams that discovered them in the coming months. Element 113 will be the first element to be named in Asia.

    这些新元素暂时以它们的占位符来命名。今后几个月,这些元素的官方名称将由发现它们的团队来命名。113号元素将会是在亚洲命名的第一种元素。

    “The chemistry community is eager to see its most cherished table finally being completed down to the seventh row,” said Professor Jan Reedijk, president of the Inorganic1 Chemistry Division of IUPAC.

    国际纯粹与应用化学联合会无机化学部门主席Jan Reedijk声称,“化学界都急迫地想看到,他们最珍视的周期表能完整到了第7排。”

    “IUPAC has now initiated2 the process of formalising names and symbols for these elements temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118).”

    国际纯粹与应用化学联合会现在已经开始为这些元素正式命名并赋予符号。这些元素暂时被称为Uut(113号元素)、Uup(115号元素)、Uus(117号元素)和Uuo(118号元素)。

    New elements can be named after a mythological3 concept, a mineral, a place or country, a property or a scientist. The four new elements, all of which are synthetic4, were discovered by slamming lighter5 ­nuclei into each other and tracking the following decay of the radioactive superheavy elements.

    新元素可以依据某一虚拟概念、矿物、发现地点、发现者的国籍、元素的特性或者某个科学家来命名。这四种新元素都是人造的,是由火花与原子核相互撞击并且循着放射性超重元素衰变的轨迹而发现的。
