Tennessine is a chemical element with the symbol Ts and atomic number 117. It is a synthetic element, meaning it has never been found in nature.
Tennessine was first created in 2010 by a team of scientists at the Joint Institute for Nuclear Research in Dubna, Russia. They bombarded americium-243 with calcium-48 nuclei to create tennessine-294.
Tennessine is a radioactive element with a very short half-life. The half-life of tennessine-294 is only 7.7 seconds. This means that half of the tennessine-294 atoms will decay into other elements in 7.7 seconds.
Tennessine is a very heavy element. Its atomic mass is 294.36222 amu. This makes it the heaviest element that has been created so far.
Tennessine is a member of the transactinide series. The transactinide series is a group of elements that are heavier than uranium.
