Isotopes

Unquadunium, also known as eka-protactinium or element 141, is the temporary name of a hypothetical superheavy chemical element in the periodic table in the superactinide series that has the temporary symbol Uqu and has the atomic number 141. In the periodic table of elements, it is a f-block element. As of 2012, no attempt has been made to synthesize this element.

HistoryEdit

Currently, unquadunium 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. It is also probable that, due to drip instabilities, only the lighter superactinides are physically possible and the periodic table may end soon after the island of stability expected to be centered at element 126.[3]

NamingEdit

Unquadnilium is a temporary IUPAC systematic element name derived from the digits 141. Research scientists usually refer to the element simply as element 141.
