The origin of the term "isotope" in the Greek language is a combination of the words isos (meaning "same") and topos(meaning "place"). This is in reference to the fact that all isotopes of an element occupy the same place or position in the Periodic Table. The history of isotopes as a concept began in 1913 when … See more Isotope names generally include the name of the element followed by the atomic mass. For example, the three isotopes of carbon have atomic masses of 12, 13, and 14 and are named Carbon-12, Carbon-13, and Carbon-14, … See more There are many ways in which different isotopes may be classified including radioactive isotopes, long-lived isotopes, stable isotopes, and … See more Webradioactive isotope, also called radioisotope, radionuclide, or radioactive nuclide, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. A brief treatment of radioactive isotopes follows. For full …

WebThe broken-pair-approximation (BPA) method is applied successfully to the even nickel isotopes. The BPA wave functions are generated in the configuration space containing four (2p32, 1f52, 2p12, 1g92) valence single-particle orbitals, using the core-renormalized Tabakin interaction. WebIsotopes are distinct nuclear species (or nuclides, as technical term) of the same element.They have the same atomic number (number of protons in their nuclei) and … WebApr 11, 2024 · Superheavy S isotopes from glacier-associated sediments of the Neoproterozoic of south China: Oceanic anoxia or sulfate limitation? notice of award nih
