In search of superheavies — Science Information, September 8, 1973
Physicists and chemists had been actively on the lookout for superheavy parts, components with atomic weights and numbers more than the 105 [elements] referred to now. Result of two searches are reported … none have been discovered…. Long run searches should contain direct fusion of heavy nuclei by means of using one in opposition to every other in heavy-ion accelerators.

Particle accelerators had been an important for developing superheavies past parts 104 and 105. Only a 12 months later, part 106, seaborgium, emerged from collisions of oxygen ions and californium atoms — regardless that its discovery wasn’t formally showed till twenty years later (SN: 3/19/94, p. 180). Parts 107 thru 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 looking to create parts 119 and 120 (SN: 3/2/19, p. 16). Forming heavier parts and pushing identified superheavyweights to their limits may just disclose insights into the forces that bind atoms in combination and the abnormal chemistry of probably the most excessive parts.
