Bohrium Element in Periodic Table | Atomic Number Atomic Mass

Bohrium Element:

Bohrium is a synthetic chemical element and it is a member of group 7 and period 7 in the periodic table. The atomic number of bohrium is 107 and it is indicated by symbol is Bh. Bohrium can be created in a laboratory but is not found in nature. Bohrium is the heaviest member of group 7 and fifth member of the 6d series of transition metals in the periodic table. Bh has no stable or naturally occurring isotopes. Several radioactive isotopes have been synthesized in the laboratory, either by fusing two atoms or by observing the decay of heavier elements. Isotopes have shorter half-lives. ²⁶⁴Bh, ²⁶⁵Bh, ²⁶⁶Bh, and ²⁷¹Bh are more stable at around 1 s, and ²⁶⁷Bh and ²⁷²Bh have half-lives of about 10 s. 

Uses Of Bohrium Element:

• Bohrium is used only for research.
