Atomic Mass: How to Calculate Isotope Abundance

WebRadioactive decay law: N = N.e-λt The rate of nuclear decay is also measured in terms of half-lives. The half-life is the time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. Web4 feb. 2024 · List the mass number of an element after its name or element symbol. For example, an isotope with 6 protons and 6 neutrons is carbon-12 or C-12. An isotope with 6 protons and 7 neutrons is carbon-13 or C-16. Note the mass number of two isotopes may be the same, even though they are different elements. Web2 jun. 2024 · You can find the number of neutrons if you know the isotope of the atom.
