Berkelium is a solid metal at room temperature.
Berkelium is an artificial chemical element, not found in rocks.
Berkelium is only an artificial element.
Berkelium is a very rare, artificial element, impossible to found in the nature.
berkelium
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.

Berkelium is a chemical element containing as any other elements protons, neutrons and electrons.
The electron configuration of berkelium is [Rn]5f97s2.
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.
Berkelium is a radioactive metal that is typically shiny in its pure form due to its metallic properties. However, it quickly tarnishes in air, which may give it a dull appearance over time.
Berkelium is a synthetic chemical element that is typically produced in a laboratory by bombarding heavy target elements with neutrons. It does not occur naturally in significant amounts.
