Interesting Bohrium Facts: Bohrium is one of the later discoveries, as it was not fully discovered until A German research team at that time isolated it under the direction of Peter Armbruster and Gottfried Munzenberg in Darmstadt. The element was named after Danish nuclear physicist Niels Bohr, and was originally given the longer name nielsbohrium.
It was synthesized when the team bombarded a bismuth isotope, Bi with a chromium isotope, Cr The resulting reaction produced five atoms of bohrium. A measure of how difficult it is to deform a material. It is given by the ratio of the shear stress to the shear strain. A measure of how difficult it is to compress a substance. It is given by the ratio of the pressure on a body to the fractional decrease in volume. A measure of the propensity of a substance to evaporate.
It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. This Site has been carefully prepared for your visit, and we ask you to honour and agree to the following terms and conditions when using this Site.

Appearance The description of the element in its natural form. Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Uses and properties. Image explanation. The abstracted symbol and patterns are based on the, now iconic, atomic model proposed by Niels Bohr in At present, bohrium is of research interest only.
Biological role. Natural abundance. Bohrium does not occur naturally and only a few atoms have ever been made. It will probably never be isolated in observable quantities. This involved the bombardment of bismuth with atoms of chromium. Help text not available for this section currently. Elements and Periodic Table History. They published the results of their successful run in and submitted a discovery claim. Now followed a period of negotiation to establish who discovered elements first and thereby had the right to name it.

Named after the physicist Lise Meitner, one of the first scientists to recognize that uranium could undergo nuclear fission. Named after the Roman god, Mercury Hermes in Greek mythology , the swift-moving messenger of the gods; the symbol Hg is from the Latin name, hydragyrum , "liquid silver".
German: kupfernickel , "Old Nick's copper" i. Named after Niobe, a character in Greek mythology, who was the daughter of Tantalus, because of the similarity of niobium to tantalum; also known as "columbium" Cb by metallurgists [see page on Discoverers of the Elements ]. Greek: osme , "odor" because of its nasty smell, which is actually caused by osmium tetroxide. Named after the asteroid Pallas, which had been discovered the year that the metal was first isolated.
Spanish: platina , "little silver" because it was first known to Europeans as an unworkable silver-like metal found alongside gold in some deposits. Named after the English word for the mineral potassium carbonate, potash which is found in high concentrations in wood ashes ; the symbol K comes from the Latin name, kalium.
Latin: radius , "ray" because of its ability to glow in the dark with a faint blue light. Named after the physicist Ernest Rutherford, discoverer of the atomic nucleus, and a pioneer in the study of nuclear physics. Named after the chemist Glenn T. Anglo-Saxon: siolfur ; the symbol Ag comes from the Latin name, argentum.
The namesake of Bohrium, Niels Bohr, was awarded the Nobel Prize in for his work on the structure of atoms. In the Bohr atomic model, electrons are depicted as having specific orbits around the nucleus.
Bohr was the first person to recognize that electrons had separate orbits in an atom. His atomic model is perhaps the most recognizable, though other atomic models have since been accepted as more accurate depictions of the structure of an atom.
