U.S. back in race to make unknown, superheavy elements

Good news!

"... From 1936 through 1976, LBNL [Lawrence Berkeley National Laboratory] used its atom smashers to discover 16 elements, from element 43 (technetium) to 106 (seaborgium). But in the decades that followed the axis of superheavy research shifted to facilities in Germany, Japan, and Russia, which collectively discovered the last 12 elements. ..."

"Key Takeaways
  • Scientists at Berkeley Lab have successfully made known element 116 (livermorium) using a titanium beam for the first time, a breakthrough that enables the lab to try to make new element 120.
  • If discovered, element 120 would be the heaviest atom ever created and fall on the 8th row of the periodic table.
  • Element 120 is near the theorized “island of stability,” where superheavy elements could be long-lived – enabling scientists to better study them.
...
The recipe for making superheavy elements is simple in theory. You smash together two lighter elements that, combined, have the number of protons you want in your final atom. It’s basic math: 1+2=3.
In practice, of course, it’s incredibly difficult. It can take trillions of interactions before two atoms fuse successfully, and there are limitations on what elements can reasonably be turned into a particle beam or target. ..."

A New Way to Make Element 116 Opens the Door to Heavier Atoms Researchers at Berkeley Lab’s 88-Inch Cyclotron successfully made superheavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.
