বিষয়ে Tennessine
Tennessine was produced by bombarding berkelium-249 with calcium-48 ions. The berkelium target took 250 days to produce at Oak Ridge. Only about 15 atoms have been detected.
Uses & Applications
No practical applications. Scientific research only.
মজা কথা
Creating tennessine required producing berkelium over 250 days at Oak Ridge, then shipping it to Russia -- a remarkable collaboration.
