Tennessine is a synthetic chemical element; it has symbol Ts and atomic number 117. It has the second-highest atomic number and joint-highest atomic mass of all known elements and is the penultimate element of the 7th period of the periodic table.
tennessine (Ts), artificially produced transuranium element of atomic number 117. In 2010 Russian and American scientists announced the production of six atoms of tennessine, which were formed when 22 milligrams of berkelium-249 were bombarded with atoms of calcium-48, at the cyclotron at the Joint Institute for Nuclear Research in Dubna, Russia

May 21, 2023 · Tennessine is a synthetic radioactive element with atomic number 117 and element symbol Ts. It is the second heaviest element created to date, with isotope half-lives less than one second. So, it is very rare and doesn’t stick around very long.
Tennessine (formerly Ununseptium meaning "one-one-seven-ium" in Latin) is a radioactive superheavy man-made chemical element. It has a symbol Ts and atomic number of 117. It is the second heaviest element of all, and is the second to last element.
Apr 1, 2019 · Tennessine is element 117 on the periodic table, with the element symbol Ts and predicted atomic weight of 294. Element 117 is an artificially produced radioactive element that was verified for inclusion on the periodic table in 2016. Interesting Tennessine Element Facts. A Russian-American team announced the discovery of element 117 in 2010.
Tennessine was made by a fusion reaction of element 20 with element 97: calcium-48 with berkelium-249. In the first synthesis of tennessine, calcium ions were formed into a beam in a cyclotron (a particle accelerator) and fired at a target layer of berkelium deposited 300 nm thick on titanium foil.
Tennessine is a synthetic chemical element with the symbol Ts and atomic number 117. It is the second-heaviest known element and the penultimate element of the 7th period of the periodic table.
On Novemer 28th, 2016 element 117 was named Tennessine with the symbol (Ts). The Tennessee region of the United States is home to Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee at Knoxville, all of which contributed to superheavy element research.
