This article is about a set of undiscovered elements. Once they are discovered, this article will be edited with more information.

The superactinide series is a group of elements that have predicted properties that may be similar to those of the original actinides. The superactinides are located under the actinides in the periodic table and they belong in period 8.

They start with element 121, which is believed to be relatively stable. The elements after that are believed to have half-lives ( time it takes half an element to decay ) very close to the 1 microsecond border. Element 119 could even be the the last element we can find with current tech.
