- The lifetimes of the first ‘transuranium ‘elements - such as plutonium, curium and californium - were very close to the values predicted by the liquid-drop model.’
- Following up on berkelium, dubnium and californium, researchers at the University of Berkely in California, stumbled upon am element with atomic number 117 about a year ago.
- For example, researchers at the Berkeley laboratory first discovered elements 97 and 98 and then suggested naming them berkelium and californium in honor of Berkeley, California, where the research was done.
1950s: named after University of California at Berkeley (where it was first made) + -ium.
