The official Periodic Table of the Elements is one step closer to adding element 117 to its ranks. That’s thanks to an international team of scientists that was able to successfully create several atoms of element 117, which is currently known as Ununseptium until it’s given an official name.

The paper for this experiment has been published in Physical Review Letters.

Ununseptium, like many superheavy elements near the end of the periodic table, is incredibly unstable, existing only for fractions of a second before decaying into other elements. In fact, scientists didn’t actually observe any atoms of element 117 – its existence was confirmed by its decay. Indeed, the elements that 117 decays to themselves decay.

As part of the Periodic Table, Ununseptium would be considered a Group VII element, putting it in the same family as flourine, bromine and chlorine.
