Beryllium dust is extremely POISONOUS. Because of this, it has never been used in mass production.

Is berkelium shiny or dull?
Berkelium has a silvery appearance.
Is berkelium explosive?
Berkelium is not explosive; but a sufficient quantity of berkelium (practically impossible to be obtained) can reach the critical mass.
What does berkelium do?
Berkelium is a radioactive element with the atomic number 96. No practical uses for berkelium have been found and the small amounts that have been created have been used exclusively for scientific research.
What two elements did Seaborg's group produce and what are they symbols?
Seaborg actually produced more than two. He produced Plutonium (Pu), Americium (Am), Curium (Cm), Berkelium (Bk) and Califormium) (Cf).
