Bohrium like many supersized elements it is very unstable and has a half life of around 61 seconds. Little is known about its physical properties and much of the science involving it are predictions. Much of the science of Bohrium is based on the reactions of Rhenium. Claimed by Russian scientists in 1976 who bombarded chromium and manganese atoms together. It was not until 1981 in Darmstadt, Germany that Bohrium was confirmed. Bohrium has no stable or naturally occurring isotopes and can only be synthesised in the lab. As so little of it has been created the melting and boiling point have not been analysed.
