What element has 53 protons and 74 neutrons? What is relative abundance of isotopes? What unstable isotopes are used for radiocarbon dating? What is the mass number of the isotope lithium-7? What element with a mass number of 100 has 56 neutrons in its nucleus? How many stable isotopes ...
Stable isotopes indicate the predominance of high-elevation precipitation that undergoes little evaporation prior to groundwater recharge. 稳定同位素显示, 几乎无蒸发的高海拔降水是地下水的主要补给来源。 springer Lead-202 is an unstable isotope; lead-204, lead-206, lead-207 and lead-208 are stabl...
In the region of unstable nuclei, we are confronted with a new problem when attempting to find proton and neutron densities separately from elastic proton scattering data, since electron scattering data for unstable nuclei are not presently available. We introduce a new means of determining proton ...
The stable isotopes have nuclei that do not decay to other isotopes on geologic timescales, but may themselves be produced by the decay of radioactive isotopes. Radioactive (unstable) isotopes have nuclei that spontaneously decay over time to form other isotopes. For example, 14C, a radioisotope...
