Berkelium(III) nitrate

Summary

Berkelium(III) nitrate is the berkerlium salt of nitric acid with the formula Bk(NO3)3. It commonly forms the tetrahydrate, Bk(NO3)3·4H2O, which is a light green solid. If heated to 450 °C, it decomposes to berkelium(IV) oxide.

Production and usesEdit

Berkelium(III) nitrate is produced by the reaction of berkelium metal or the hydroxide with nitric acid.[1] This compound has no commercial uses, but was used to synthesize the element tennessine. The aqueous compound was painted onto a titanium foil and was bombarded with calcium-48 atoms to synthesize the element tennessine.[2]
