Dubnium-Properties And Applications

Dubnium is a synthetic chemical element with the symbol ‘Db’ and atomic number 105. It is a highly radioactive, metallic element in the transactinide series of the periodic table. Dubnium was first synthesized in 1967 by a team of Russian scientists at the Joint Institute for Nuclear Research in Dubna, from which its name is derived. Due to its extremely short half-life and limited production, little is known about its properties and applications.
