Flerovium Crewneck Sweatshirts

An inspired Flerovium design. Flerovium is a superheavy artificial chemical element with symbol Fl and atomic number 114. It is an extremely radioactive synthetic element. The element is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1998.

Fl is the periodic table element symbol for the radioactive element flerovium.

The orbitals are swirling in Storistir to make holiday ornaments! Scientists were hoping to create an isotope of Flerovium within the theoretical island of stability with a half life of thousands of years. However, the making of this isotope has been illusive so far.

Flerovium has a "long" half-life of 30 seconds. Scientists were hoping to find an "island of stability" isotope so transfermium elements could last long enough to be studied better.

Periodic table. This table includes the elements Copernicium, Flerovium and Livermorium, which have been added since 2010. It is against a space background illustrating the composition of the universe as we know it.

There are 15 transactinides currently, which are all man-made, short-lived and difficult to create. Can you name all 15?
