Berkelium

What it is

Berkelium is a synthetic radioactive element in the actinide series [1], [15]. It can exhibit +3 or +4 valence states [1].

Anxiety level

High. Berkelium is a radioactive element, and many sources focus on the dangers and safety precautions necessary when handling it [15], [45].

Cultural claims

• Berkelium is named after Berkeley, California, where it was first synthesized [23].

Source sentiment

Sources generally present berkelium objectively, focusing on its chemical and physical properties, synthesis, and potential hazards due to its radioactivity [1], [15].

Origin

Berkelium was first synthesized in December 1949 at the University of California, Berkeley, by bombarding americium with alpha particles [23], [20].

First appeared: 1949

Studies

Nuance

The health hazards posed by radioactive elements such as berkelium have been a major hurdle to their research [15]. As a result, comparatively little is known about them and their chemistries [15].
