Isotopes

Unhexseptium, also known as eka-ununseptium or element 167, is the temporary name of a hypothetical superheavy chemical element in the periodic table that has the temporary symbol Uhs and has the atomic number 167. In the periodic table of elements, it is a p-block element and the second last one of the 8th period. As of 2012, no attempt has been made to synthesize this element. It is predicted to be a halogen.

HistoryEdit

Currently, unhexseptium 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

No name has yet been officially suggested for the element. According to current guidelines from IUPAC, the ultimate name for all new elements should end in "-ium", which means the name for unhexseptium may end in "-ium", not "-ine", even if unhexseptium turns out to be a halogen, which traditionally have names ending in "-ine".[3]
