WebQuestion: The element rhenium (Re) has two naturally occurring isotopes, ^185Re and ^187Re. with an average atomic mass of 186.207 amu. Rhenium is 62.60% ^187Re, and the atomic mass of ^187Reis 186.956 amu. Calculate the mass of ^185Re. Show transcribed image text Expert Answer % of 185 Re = 100 - 62.6 = 37.4 % avera … View the full answer WebEstimates of current demand for 225 Ac are less than 185 GBq (5 Ci) per year, however, this is likely significantly tempered by both supply constraints and cost. While predicting future demand is difficult, it can be estimated to grow by about 200 to 400 GBq per year (about 5 to 10 Ci per year) for each 225 Ac-based therapy that is approved for clinical use 4 .

WebIn the nucleus of each atom of uranium-235 (U-235) are 92 protons and 143 neutrons, for a total of 235. The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. cops season 5 intro

Web7 apr. 2024 · Neutron stars are typically about 20 km (12 miles) in diameter. Their masses range between 1.18 and 1.97 times that of the Sun, but most are 1.35 times that of the Sun. Thus, their mean densities are extremely high—about 10 14 times that of water.

It is one of the rarest elements on the Earth with an abundance of something like 1 part per million. It is also one of the densest elements, following only platinum, iridium and osmium and it is one of the highest melting point elements exceeded only by tungsten and carbon. famous people 1997
