Where ununpentium found?
Unnilpentium is now officially named as Dubnium (Db) after the Russian town of Dubna. It is not found in nature and is synthesized in the laboratory.
Ununpentium is not naturally occurring and can only be made under extreme lab conditions in miniscule amounts. The half life of Ununpentium is extremely short, therefore any of this substance which CAN be made would not exist for long. Therefore, the cost is essentially whatever expense is incurred during the procedure of artificially creating the material. This would likely be a vast number.
