To indicate that standard atomic weights of elements with two or more stable isotopes are not constants of nature, the Table of Standard Atomic Weights 2013 lists atomic-weight intervals for the standard atomic weights of 12 such elements (B, Br, C, Cl, H, Li, Mg, N, O, S, Si, and...
To indicate that standard atomic weights of elements with two or more stable isotopes are not con-stants of nature, the Table of Standard Atomic Weights 2011 lists atomic-weight intervals for the stan-dard atomic weights of 12 such elements (B, Br, C, Cl, H, Li, Mg, N, O, S, Si,...

The total REE contents of the Lower Tal phosphorites cover a wide range (94 to 789 ppm, see Table 1), with two samples (SK-6 and MA-54) recording >700 ppm and one (DU-8) having <100 ppm of REE. ΣREEph/ΣREEsh ratios (ph=phosphorite; sh=Post Archean Average Shale (PAAS), ...
One of only two cis-uranic elements with no stable isotopes, it (technetium) had to be synthesised to be discovered (hence the name). The other one is protactinium. @ndbrning The first long-lived isotope of protactinium was discovered by Otto Hahn and Lise Meitner in 1917. 80 years later...
Practice Question Carbon has an atomic number of six, and two stable isotopes with mass numbers of twelve and thirteen, respectively. Its atomic mass is 12.11. Figure 2. Carbon-12 and carbon-13 How many neutrons do carbon-12 and carbon-13 have, respectively? Show Answer ...
Isotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few neutrons. To learn more about the Types, Examples, Physic
They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms; that is, that their atoms could not combine with those of other elements to form chemical compounds. Their electronic structures ...
