Did You Know?
It is named in honor of Alfred Nobel, the inventor of dynamite and the founder of the Nobel Prizes.
The element's discovery was complex and controversial, with competing claims from research teams in Sweden, the United States, and the Soviet Union (now Russia).
It is the 10th transuranic element to be synthesized.
Experiments have shown that nobelium behaves differently in solution than other actinides, sometimes showing properties more like alkaline earth metals.
