Unbinilium facts for kids
Unbinilium is a hypothetical (theoretical or imagined) element of the periodic table. It is also known as eka- radium. The atomic number of this element is 120. It has the symbol Ubn. The name Unbinilium and the symbol Ubn are temporary IUPAC names. This name and symbol exist until a permanent name is decided. It is expected to be a S-block element and an alkaline earth metal. It is the second element in the eighth period of the periodic table.
This element is not synthesized (obtained or discovered) yet. A German team of GSI Helmholtz Centre for Heavy Ion Research attempted a research on 2011. It suggested a possible production of 299Ubn. But it was incomplete. Attempts were planned by Russian, Japanese, French teams. These were planned in 2017-2020. Experiments from the attempts showed that 8th period elements were difficult to synthesize. Unbinilium is expected to be the last element that can be synthesized through current technology.

A chart of nuclide stability as used by the Dubna team in 2010. Characterized isotopes are shown with borders. Beyond element 118 (oganesson, the last known element), the line of known nuclides is expected to rapidly enter a region of instability, with no half-lives over one microsecond after element 121. The elliptical region encloses the predicted location of the island of stability.
