So, in February 2004 OIYAIO and Lawrence Livermore National Laboratory received 115 item. It happened in February 2004. In addition, scientists announced the discovery of element 113, formed in the process of decay of element 115. Nevertheless, the International Union of Pure and Applied Chemistry did not consider the submission of evidence of opening 113 sufficient element.

115 and 117 members received the preliminary title and Ununpentium Ununseptium. 113 element is likely to be called "Japan." By the way, this element first discovered and named by researchers from Asia. 118 item previously named ununoctium (ununoctium).

Now, after the official recognition of the discovery of these elements, the seventh period of the periodic table is full.
