What are the features of bohrium, hassium and meitnerium?

 

 

                   Bohrium is a synthetic element named after Danish physicist Niels Bohr, who was the first scientist to correctly explain atomic structure. Bohrium is one of the later discoveries, as it was not fully discovered until 1987.

                  A German research team under the direction of Peter Armbruster and Gottfried Munzenberg successfully synthesized the element at Darmstadt, Germany. It has the atomic number 107, and is represented as Bh.

 

 

 

 

 

                   Hassium is named after the German state of Hesse, home of the German Nuclear Research Institute. Peter Armbruster, Gottfried Munzenberg and their colleagues discovered hassium in 1984, around the same time they discovered bohrium. A Russian team was the first to attempt to synthesize hassium in 1978. However, they were unsuccessful. It has the atomic number 108, and it is represented as Hs.

 

 

 

 

                Meitnerium is an intensely radioactive synthetic element. It is named after Lise Meitner, Austrian physicist, who first suggested that radioactive atoms could spontaneously split apart releasing energy. Meitnerium was discovered by the same team of German researchers who isolated hassium and bohrium. Its atomic number is 109, and symbol is Mt.
