WebMass numbers of typical isotopes of Radium are 226. Atomic Mass of Radium Atomic mass of Radium is 226 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. WebThis process gives a way to age rocks, by measuring the isotopes of rubidium and strontium with mass spectrometry, then calculating the ratios of the radioactive forms to their decay products. Although it is chemically interesting, the element has relatively few commercial applications at present, but the amount of research activity suggests many …
WebElement 103, lawrencium, was discovered in 1961 by Ghiorso and co-workers [GHI61]. They produced a new 8.6-MeV alpha-emitting isotope with a 8±2 second half- life in the reactions ofnB and10B with252Cf. This isotope was later assigned to258Lr. Since that time, a total of ten isotopes have been produced and identified, (See Table I).
