Borium is an unstable radioactive chemical element with atomic number 107. Isotopes with mass numbers from 261 are known up to 272. The synthesis of the 107th element was first reported in 1976 by the group of Yuri Oganesyan from the Joint Institute for Nuclear Research in Dubna. The technique of this work was to study the spontaneous fission of the products of the fusion reaction of bismuth and chromium nuclei. & Nbsp;
