The first experiments were started in 1976 by a Soviet team led by Y. Oganessian at the Joint Institute for Nuclear Research at Dubna, who produced isotope Bohrium-261. With heavy nuclei of Chromium-54. In this experiment the was performed by bombarding of the fast rotating cylinder coated by a thin layer of Bismuth-204. By a tangentially directed stream of Chromium-54. German scientists have offered name Nielsbohrium.
Element Iridium, Ir, Transition Metal. Syssertskite, platinum, rhodium and ruthenium nevyanskite and aurosmirid. They contain also several other mineral forming elements and belong to the solid solutions class.
Element Rhodium, Rh, Transition Metal. Was discovered in 1803 by William Hyde Wollaston, soon after his discovery of palladium. Wollaston dissolved raw platinum in aqua regia. The acid surplus was neutralized by caustic soda. He then precipitated the platinum by adding ammonium chloride, NH. Cl; palladium was removed as palladium cyanide after treating the solution with mercuric cyanide.
Element Ruthenium, Ru, Transition Metal. Klaus fused it with saltpeter and isolated the water soluble part. The insoluble part was treated by aqua regia. Then separated the part of crude platinum that was insoluble in aqua regia.
The temporary name for this element offered by IUPAC was Unniloctium. After Otto Hahn proposed in August 1994. However, finally the final name Hassium.
Element Rhenium, Re, Transition Metal. Is the rarest and much dispersed trace element. Its average abundance is 7x10. Is the rarest element with stale isotopes.

My last post was way back in September and there have been so many changes since then. Thursday, September 22, 2011.

Friday, May 25, 2012. Day 4 - Pure Dirt. From the hotel and headed southeast on 541. This stretch of pavement was somewhat familiar, as we had come this way a few days prior in the other direction. Well paved and chock full of long sweeping turns, we were on the throttle hard, enjoying the fresh, cool morning air.
In honor the American chemist G. Seaborg was confirmed by IUPAC for the element 106.
