Web17 de jun. de 2024 · Isotopes are variants of the same element that have different numbers of neutrons (and thus potentially different physical properties). They do, however, tend to have the same chemical … WebIsotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

WebHá 1 dia · The radioactive isotope forms continuously in the upper atmosphere as cosmic rays—high-energy particles from space—collide with gas molecules, spawning neutrons. When one of these neutrons knocks out a proton in a nitrogen atom, that nitrogen is transformed into 14 C. As it inhaled CO 2, the cedar had incorporated the 14 C into its … 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. biphasic t wave in v3
