Four new chemical elements have been officially added to the periodic table.

四种新的化学元素被正式加入到元素周期表中。

The International Union of Pure and Applied¹ Chemistry announced names of the new elements earlier this week. They are Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og).

本周早些时候，国际理论与应用化学联合会公布了四种新元素的名称。它们分别是第113号 (Nihonium)、第115号(Moscovium )、第117号(Tennessine)以及第118号元素 (Oganesson)。

The names were chosen by the scientists who discovered them. All of the elements are man-made, created in labs by nuclear researchers. Those researchers are from Japan, Russia and the United States.

这些新元素的名字都是由发现它们的科学家选择的。所有元素均为人造元素，由核研究员在实验室里创造出来的。这些研究人员来自日本、俄罗斯和美国。

Moscovium is named after Moscow, the Russian capital. Oganesson is named in honor of the 83-year-old Russian researcher Yuri Oganessian. Oganesson is only the second element to be named after a living scientist.

115号元素Moscovium以俄罗斯首都莫斯科命名。118号元素 Oganesson是为了纪念83岁的俄罗斯研究人员尤里·奥甘尼西亚。这是第二个以一位在世的科学家名字命名的元素。

Tennessine is named after the American state of Tennessee. American researchers named the new element. They work for Oak Ridge² National Laboratory and Vanderbilt University, both of which are based in the state.

117号元素Tennessine是以美国田纳西州命名的。这种新元素由美国研究人员命名。他们来自橡树岭国家实验室和范德比尔特大学，两家机构都位于田纳西州。

A group of Japanese researchers came up with the name for the fourth new element, Nihonium. The word “Nihon” means Japan in Japanese.

日本研究人员命名了第四种新元素——113号元素Nihonium。“Nihon”这个词在日语中是“日本”的意思。

Elements can be named for an idea or character in mythology³, a mineral, a place, a scientist or a property of the element.

元素可以用神话中的人物或者观念、矿物、地点、科学家的名字或者元素的特性来命名。

The chemistry union usually likes names that are easy to translate across major languages. The names must have endings like “-ium,” “-ine” or “-on,” depending on the grouping of elements they belong to.

化学联合会通常会喜欢那些容易在几种主要语言之间进行翻译的名字。根据元素所属的组别，这些名字必须以“-ium” “-ine” 或者“-on”结尾。

The four new names will now be under consideration for five months to give time for any possible objections.

这四个新的元素名字将会经过五个月的审核，为任何可能的异议留出时间。
