Ghiorso updates a periodic table in 1961 with the newly discovered element lawrencium while co-discoverers Robert Latimer, Torbjorn Sikkeland and Almon Larsh look on. In the mid-1950s it became clear that to extend the periodic chart any further, a new accelerator would be needed, and the Berkeley Heavy Ion Linear Accelerator (HILAC) was built ...
[7] His newer technique, termed "hot fusion" (also unrelated to nuclear fusion as an energy process), helped to discover elements 113 to 118, completing the seventh row of the periodic table. [7] The technique involved bombarding calcium into targets containing heavier radioactive elements that are rich in neutrons at a cyclotron. [27]
Elemental arsenic was discovered in the 13th century by Albertus Magnus. [14] Antimony was well known to the ancients. A 5000-year-old vase made of nearly pure antimony exists in the Louvre.
