What is Period 8 element?
A row of the [[periodic table]]. No period 8 elements have been proven to exist. These elements are almost certainly too big to exist in nature, so they would be [[synthetic element]]s. They would probably [[radioactive decay|decay]] very quickly, because of [[radioactivity]], so they would have very short [[half-life (element)|half-lives]]. However, some scientists believe that an [[island of stability]] may exist would be part of a new category of elements, called [[superactinides]].<ref>{{Cite web|last=Krämer|first=Katrina|date=2016-01-28|title=Beyond element 118: the next row of the periodic table|url=https://www.chemistryworld.com/news/beyond-element-118-the-next-row-of-the-periodic-table/9400.article|access-date=2022-09-06|website=Chemistry World}}</ref> These range from 120 to 153 (atomic number). An example of a short half-life: the [[isotope]], <sup>260</sup>[[Sg]], has a [[half-life]] of approximately y 4 [[ms]] (or 4 thousandths of a second);<ref>{{Cite web|date=2014-07-17|title=11.2: Half-Life|url=https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Basics_of_General_Organic_and_Biological_Chemistry_(Ball_et_al.)/11%3A_Nuclear_Chemistry/11.02%3A_Half-Life|access-date=2023-08-26|website=Chemistry LibreTexts|language=en}}</ref> ==References== {{reflist}} [[Category:Chemical elements]]
