Trying to find superheaviesScience Information, September 8, 1973

Physicists and chemists have been actively looking for superheavy parts, substances with atomic weights and numbers larger than the 105 [elements] now recognized. Outcomes of two searches are reported … none had been discovered…. Future searches should contain direct fusion of heavy nuclei by driving one towards one other in heavy-ion accelerators.

Particle accelerators have been essential for creating superheavies past parts 104 and 105. Only a yr later, component 106, seaborgium, emerged from collisions of oxygen ions and californium atoms — although its discovery wasn’t formally confirmed till twenty years later (SN: 3/19/94, p. 180). Components 107 via 118 have since made their debut, with a number of becoming a member of the periodic desk as lately as 2016. Scientists at the moment are attempting to create parts 119 and 120 (SN: 3/2/19, p. 16). Forming heavier parts and pushing recognized superheavyweights to their limits may reveal insights into the forces that bind atoms collectively and the weird chemistry of probably the most excessive parts.
