Berkelium is an artificial element, extremely rare, unstable and the preparation is very difficult.
Berkelium is extremely rare, radioactive and unstable; berkelium is not for sale.
Berkelium is a very rare, artificial element, impossible to found in the nature.
It is an artificial element that is very rare and difficult to create.
Berkelium is radioactive and emits harmful radiation, which can be a weakness when handling and storing this element. Additionally, berkelium is rare and expensive to produce, limiting its practical applications.
Curium and berkelium are artificial chemical elements, very rare, unstable and radioactive. Members of the actinides group.
Berkelium currently has no uses except for scientists to use for basic research.
Berkelium is a radioactive metal that is silvery-white in color. It is a rare earth element and is typically found in trace amounts in nature. Berkelium is highly reactive, especially in its divalent state.
The total production of berkelium, around the world, during the last 60 years, was only some grams.
The most common isotope , berkelium-249, has 152 neutrons.Number of neutrons = Mass number of an isotope - 97
The most common isotope , berkelium-249, has 152 neutrons.Number of neutrons = Mass number of an isotope - 97
Berkelium has the electronegativity 1,3 in the L. Pauling scale; it is sufficiently reactive to react with the majority of other elements but the chemistry of Bk is not so studied because Bk is very rare. Compounds with oxygen, halogens, hydrogen, nitrogen, sulfur, arsenic, phosphorous, etc. are now known.
The cost of berkelium is not readily available since it is a highly radioactive and rare element that is mainly produced in laboratories for research purposes. It is not typically bought or sold commercially for everyday use.
