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). 做好准备吧！2017年你将面对周边全新的元素周期表，因为又有4种元素正式加入第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. 从今年一月份我们就听说过这4种新元素了，但国际理论（化学）与应用化学联合会（IUPAC）终于宣布了正式批准其命名，有了公告，我们就可以撕下所有周期表贴图再找些新的换上了。 |
