The first nuclear reactions used to obtain berkelium-249 were:
Pu-239(4n, gamma)Pu-243--------beta-------Am-243(n, gamma)Am-244-----beta-----Cm-244(5n, gamma)
Cm-249--------beta----------Bk-249
Berkelium is a metal. It is a transuranium element and is part of the actinide series on the periodic table.
Normal phase berkelium is solid. It is a radioactive metallic element that is part of the actinide series. Berkelium does not occur naturally on Earth and is primarily produced in nuclear reactors.
The electron configuration of berkelium is [Rn]5f97s2.
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.
