Bohrium is a synthetic element that is not present in the environment at all. The German discoverers at GSI proposed the name Nielsbohrium (symbol Ns) after Niels Bohr. IUPAC are happy to name an element after Bohr but suggest bohrium ( Bh ) on the grounds that the first name of a person does not appear in the names of any other element named after a person. This seems to have been accepted by all concerned.
