Element Story - Bohrium

Bohrium is an element with atomic number 107, belonging to Group 7 of the periodic table, and is a superheavy element. All of its isotopes are radioactive, and it does not exist in nature, being synthesized artificially in particle accelerators. It was first synthesized in 1981 at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, and was named in honor of Niels Bohr, a Danish physicist who made significant contributions to the study of atomic structure and quantum mechanics. Bohrium is not utilized in daily life or industry due to the extremely small number of atoms produced and its short half-life; it is primarily used to study the nuclear structure and radioactive decay of superheavy elements. Chemically, it is expected to exhibit properties similar to manganese, technetium, and rhenium, which are also in Group 7. Limited experiments have studied its characteristic of forming volatile oxides and compounds containing oxygen. In elements with very large atomic numbers like Bohrium, relativistic effects significantly appear in electron motion due to the strong electric field of the atomic nucleus. Such research provides crucial information for understanding the chemical properties of superheavy elements and the limits of the periodic table.
