Unhexhexium, also known as eka-livermorium or element 166, is the temporary name of a hypothetical superheavy chemical element in the periodic table that has the temporary symbol Uhh and has the atomic number 166. In the periodic table of elements, it is a p-block element and the third last one of the 8th period. As of 2012, no attempt has been made to synthesize this element. It is predicted to be a chalcogen.

HistoryEdit

Currently, unhexhexium 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.

NamingEdit

Unhexhexium is a temporary IUPAC systematic element name derived from the digits 166. Research scientists usually refer to the element simply as element 166.
