Berkelium is a soft, silvery-white, radioactive actinide metal. In the periodic table, it is located to the right of the actinide curium, to the left of the actinide californium and below the lanthanide terbium with which it shares many similarities in physical and chemical properties.

Berkelium, synthetic chemical element of the actinoid series of the periodic table, atomic number 97. All berkelium isotopes are radioactive, and the only use of berkelium has been in the synthesis of heavier elements such as tennessine. The element berkelium was discovered in 1949.

Berkelium's most stable isotope, berkelium-247, has a half-life of about 1,380 years. It decays into americium-243 through alpha decay. The first visible amounts of a berkelium compound, berkelium chloride (BkCl 3 ) was produced in 1962 and weighed about 3 billionths of a gram (0.000000003 grams).

Oct 6, 2019 · All of the isotopes of berkelium are radioactive. Berkelium-243 was the first isotope to be produced. The most stable isotope is berkelium-247, which has a half-life of 1380 years, eventually decaying into americium-243 via alpha decay. About 20 …

Oct 7, 2013 · Berkelium is the eighth member of the actinide transition series. As a metal, it has a silvery appearance that rapidly oxidizes in air or oxygen at elevated temperatures, forming an oxide.

Berkelium's most stable isotope, berkelium-247, has a half-life of about 1,380 years. It decays into americium -243 through alpha decay . The first visible amounts of a berkelium compound, berkelium chloride (BkCl 3 ) was produced in 1962 and weighed about 3 billionths of a gram (0.000000003 grams).

Berkelium, the eighth member of the actinide transition series, was first produced in 1949 by Thompson, Ghiorso, and Seaborg via accelerator bombardment of 241 Am with high energy alpha particles. This generated a new electron-capture activity eluting on a chromatography column just ahead of curium.

Sep 1, 2024 · Berkelium is a synthetic element which can only be prepared in a laboratory, and till now a very small amount of berkelium has been produced. Berkelium has around 20 isotopes and all of them are radioactive in nature.

Berkelium is the 97th element in the periodic table and has a symbol of Bk and atomic number of 97. It has an atomic weight of (247) and a mass number of 233. Berkelium has ninety-seven protons and one hundred thirty-six neutrons in its nucleus, …
