Unseptnilium, also known as dvi-radium or element 170, is the temporary name of a hypothetical superheavy chemical element in the periodic table that has the temporary symbol Usn and has the atomic number 170. In the periodic table of elements, it is a s-block element and the second one of the 9th period. As of 2012, no attempt has been made to synthesize this element. It is predicted to be an alkaline earth metal.
Currently, unseptnilium goes under a systematic temporary element name. Since it is very far in the periodic table and has never been synthesized, very little is known about this element, and it is unknown whether a superheavy element like this could physically exist.
Extrapolated chemical propertiesEdit
Unseptnilium is a superheavy element, therefore it has a very large atom which is significantly radioactive. Since it is very far in the periodic table and has never been synthesized, very little is known about this element.
Taking the position in the periodic table as an alkali metal, it is predicted to be a heavier homologue to the lighter ones.
