The discovery of the new chemical element with atomic number Z=117 is presented. The isotopes 293 117 and 294117 were produced in fusion reactions between 48Ca and 249Bk. The 249Bk was produced in the High Flux Isotope Reactor and chemically separated at Oak Ridge. Decay chains involving ...
Atomic Number: 117 Atomic Symbol: Ts Atomic Weight: [294] Melting Point: Unknown Boiling Point: Unknown Discovery Element 117 was discovered in 2010 and jointly announced on April 5 of that year by scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and scientists at the...
The trouble is: the larger an atomic nucleus gets, the more its protons repel one another with their positive charges, making it, in general, less stable, or more radioactive. Element 117, for example, has a half-life of about 50 thousandths of a second, meaning that within that time ...
