又添4種元素！你的元素週期表又要更新了哦！

Get ready to ring in 2017 with a brand new Periodic Table, because four more elements have officially been added to the seventh row: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og).
做好準備吧！2017年你將面對周邊全新的元素週期表，因爲又有4種元素正式加入第7行了：nihonium（Nh）、moscovium（Mc）、tennessine（Ts）、oganesson（Og）。

We've been hearing about these four new elements since January, but the International Union of Pure and Applied Chemistry (IUPAC) has finally announced that the names have been officially approved, so we've got the go-ahead to tear down all our posters and find some new ones.
從今年一月份我們就聽說過這4種新元素了，但國際理論（化學）與應用化學聯合會（IUPAC）終於宣佈了正式批准其命名，有了公告，我們就可以撕下所有周期表貼圖再找些新的換上了。

"Following a five-month period of public review, the names earlier proposed by the discoverers have been approved by the IUPAC Bureau," the organisation announced today.
今天該組織宣佈：“經過5個月的公開審議，早先由元素髮現者提出的命名方案已由IUPAC批准通過。”

"Keeping with tradition, the newly discovered elements have been named after a place or geographical region, or a scientist," they add.
他們還補充說：“依照傳統，新發現的元素都以地方名、地理區域名或一位科學家的名字命名。”

"The ending of the names also reflects and maintains historical and chemical consistency: '-ium' for elements 113 and 115 and as for all new elements of groups 1 to 16, '-ine' for element 117 and belonging to group 17 and '-on' for element 118 element belonging to group 18."
“剛完成的命名也反映並維護了歷史和化學的一貫性：第113號和115號元素都有後綴‘-ium’，跟1至16組的所有新元素一樣；第117號元素帶有‘-ine’，屬於第17組；第118號元素有‘-on’，屬於第18組。

The teams of Russian, American, and Japanese researchers behind the four new element discoveries were then tasked with naming their respective finds, and in June, their suggestions were officially submitted for review.
發現這四種新元素的俄羅斯、美國、日本科學家團隊隨即接受了爲它們命名的任務，6月份，他們的命名建議正式提交進行審議。

To get to know our four new friends a little better, nihonium is derived from "Nihon", a Japanese word for Japan, and moscovium honours the Russian capital city, Moscow.
爲了更深入一點了解我們的新朋友：“nihonium”是由“Nihon”衍生來的，後者在日語中表示日本，而“moscovium”則是爲了向俄羅斯首都莫斯科致敬。

Tennessine is named after the state of Tennessee, known for its pioneering research in chemistry, and it marks the second US state to be honoured on the periodic table. The first was California, referenced by californium (element 98).
“Tennessine”是根據田納西州（Tennessee）來命名的，該州因化學研究成果卓越而聞名，它也是美國第二個在元素週期表中留名的州。第一個是加利福尼亞（California），第98號元素californium就是以它命名的。

Oganesson is named after 83-year-old Russian physicist Yuri Oganessian, and this is only the second time a new element has been named for a living scientist.
“Oganesson”是根據83歲的俄羅斯物理學家Yuri Oganessian的名字來命名的，這也是歷史上僅有的第二次以一個在世科學家命名新元素的案例。
