2010年,俄罗斯的研究人员宣布,他们已经合成了117号元素。这种新原子还没有命名,因为科学界在为新元素命名之前,通常要先得到来自世界各地其他研究组的统一确认。不过,除非有意外出现,117号元素应该已经在元素周期表中永久地占据了一席之地。而在此之前,从氢元素到116号元素以及118号元素都相继被发现,而今117号元素的发现,将填补了元素周期表中的最后一个空位。19世纪60年代,德米特里·门捷列夫和其他研究人员创造了元素周期表,这项伟大的发明第一次将所有已知元素进行了组织分类。不过,门捷列夫在他的元素周
In 2010, researchers in Russia announced that they had synthesized Element 117. This new atom has not been named yet, as the scientific community usually has to get uniform confirmation from other research groups around the world before naming the new element. However, element 117 should have been permanently on the periodic table of the elements unless there is an accident. Prior to this, from the hydrogen element to 116 elements and 118 elements have been found, and now 117 elements found, will fill the last slot in the periodic table. In the 1860s Dmitry Mendeleev and other researchers created the Periodic Table of the Elements, the great invention for the first time organizing all the known elements into categories. However, Mendeleev in his element week
