Among elements with a known stable isotope, only indium and tellurium similarly occur with a stable isotope in lower abundance than the long-lived radioactive isotope.. The atomic weight of Re-185 is 185.0 u, and the atomic weight of Re-187 is 187.0 u. Rhenium-185 has in its nucleus. Both Rhenium isotopes are used for medical purposes. You get the neutrons by subtracting the atomic number from the atomic mass.185 is … Used Lund Fury 1600 Tiller For Sale, It resembles manganese in chemical properties. first two years of college and save thousands off your degree. 207 Bones In Human Body, The atomic mass of rhenium is 186.2. For each of the isotopes of lead, how many protons, neutrons, and electrons are in each? All rights reserved. Isotopes With A Known Natural Abundance . d.75 protons, 110 neutrons. 2 Kierra Sheard Wedding, There are many unstable isotopes of Rhenium but Rhenium 185 is the only stable isotope. In nuclear industry boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B. Let x = the atomic weight of Re-185 and (371.9087 - x) = the atomic weight of Re-187. Union Conjunct Venus Synastry, 185 Re 187 Re. Global: G2 . Two radioactive isotopes, rhenium-186 and rhenium-188, are used to treat some liver cancers. Rhenium has only one stable isotope (Rhenium -185) which is one of the rarest elements found only in two elements of tellurium and indium. 75 protons, 75 neutrons. There was one glaring exception though, the elements in group 7. Ebenso sind keine toxischen Effekte des Metalls bekannt, es gilt als arbeitshygienisch unbedenklich. Where Is Richard M Daley Now, Which among the following represent a set of isotopes? Justin Combs Ig, 6:04 first two years of college and save thousands off your degree. Rhenium-185 (185Re) has in its nucleus: 75 protons, 110 neutrons 130 protons, 75 neutrons 75 protons, 130 neutrons 75 protons, 75 neutrons Its chemical properties will be exactly like those of U-235 6. The element rhenium (Re) exists as two stable isotopes and 18 unstable isotopes. Tacoma 2wd Locking Rear Differential, The lesson is about the discovery of the element rhenium by Masataka Ogawa, Walter Noddack, and Ida Tacke. Mass Number: Natural Abundance: Half-life: 185: 37.40%: STABLE: 187: 62.60%: 4.33×10 +10 years: Known Isotopes. Known/Given: atomic weight of Re = 186.207 u x = atomic weight of Re-185 in u (371.9087 - x) = atomic weight of Re-187 in u … 8. D) 75 protons, 110 neutrons. Rhenium is element 75 in the periodic table and in many ways a rather unusual element. Used by over Soluble salts, such as the rhenium halides or perrhenates, could be hazardous due to elements other than rhenium or due to rhenium itself. It is one of the rarest elements on the Earth with an abundance of something like 1 part per million. Portuguese Water Dog Rescue, Only tungsten and carbon are higher! Cool World Full Movie, Lanc Remastered Invalid Mac Address, Rhenium is generally considered to have been discovered by Rhenium is a silvery-white metal with one of the highest Its usual commercial form is a powder, but this element can be consolidated by pressing and In bulk form and at room temperature and atmospheric pressure, the element resists alkalis, Like tungsten and molybdenum, with which it shares chemical similarities, rhenium forms a variety of Analogous alkyl and aryl derivatives are known.
