New Element 115, Ununpentium, May Join Periodic Table
The periodic table of the elements has grown ever since the first version was published by Dmitri Mendeleev in 1869. And now scientists in Sweden suggest it’s time to add yet another element to the table.
New research confirms the existence of a super-heavy, radioactive element with atomic number 115. Its temporary name is ununpentium (Uup), as the element has yet to be named formally. The research was conducted at the GSI accelerator facility near Darmstadt, Germany, where scientists are known for having discovered six other elements since the early 1980s.
