🔬
berkelium
[ˈbɜrkəˌliːəm ]
Definition
chemical element
Berkelium is a synthetic chemical element with the symbol Bk and atomic number 97. It is part of the actinide series and is produced by bombarding americium with alpha particles. Named after the city of Berkeley, California, where it was first synthesized in 1949, berkelium is highly radioactive and has no stable isotopes. The most common isotope, berkelium-247, has a half-life of about 1,380 years. Berkelium is used in scientific research, particularly in the study of transuranic elements.

Origin of 'berkelium'
Main points about word origin
- The name comes from the city of Berkeley, California, where it was discovered in 1949.
- It was named after the university located in Berkeley, which is known for its contributions to science.
- The 'ium' ending is common in the names of elements, signifying it as a metal.
The term 'berkelium' was coined in the year 1949 by a team of scientists at the University of California, Berkeley. The name pays tribute to the city of Berkeley, where the element was first synthesized. It was created by bombarding americium with alpha particles in a cyclotron, a type of particle accelerator. Berkelium is classified as a member of the actinides, which are a series of elements characterized by their radioactivity and the filling of the 5f electron shell. The discovery of berkelium marked a significant advancement in the field of nuclear chemistry and contributed to the understanding of transuranic elements, which are elements beyond uranium in the periodic table. Its isolation was a part of the post-World War II scientific exploration into new elements and radioisotopes, driven by advancements in nuclear technology.
