Unbinilium

Unbinilium /uːnbaɪˈnɪliəm/, also known as eka-radium or simply element 120, is the temporary, systematic element name of a hypothetical chemical element in the periodic table with the temporary symbol Ubn and the atomic number 120. Unbinilium and Ubn are the temporary systematic IUPAC name and symbol, until a permanent name is decided upon. In the periodic table of the elements, it is expected to be an s-block element, an alkaline earth metal, and the second element in the eighth period.To date, all attempts to synthesize this element have been unsuccessful. Its position as the seventh alkaline earth metal suggests that it would have similar properties to the alkaline earth metals, beryllium, magnesium, calcium, strontium, barium, and radium; however, relativistic effects may cause some of its properties to differ from those expected from a straight application of periodic trends. For example, unbinilium is expected to be less reactive than barium and radium and be closer in behavior to strontium, and while it should show the characteristic +2 oxidation state of the alkaline earth metals, it is also predicted to show the +4 oxidation state unknown in any other alkaline earth metal.
