tennessine
Definition
Tennessine is a synthetic chemical element with the symbol Ts and atomic number 117. It is the second-heaviest element ever created, after oganesson.
Tennessine was first synthesized 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 member of the transactinide series. The transactinide series is a group of elements that are heavier than uranium.
The name tennessine is a reference to the state of Tennessee, where the Oak Ridge National Laboratory is located. The Oak Ridge National Laboratory is a major research facility that was involved in the discovery of tennessine.
Tennessine is a very important element for scientists. It is the first element to be created in the 7th period of the periodic table. This means that it can help scientists to learn more about the properties of elements in the heaviest periods of the periodic table.
