Major Element Isotopes - YAML
Major Element Isotopes is a comprehensive dataset of isotopes (atomic nuclei with different mass numbers) for important elements from atomic number 1 to 94. It distinguishes between stable and radioactive isotopes, including physical properties such as natural abundance and half-life. The data covers isotopes essential for science, medicine, and energy applications, ranging from hydrogen isotopes (protium, deuterium, tritium) to isotopes of uranium and plutonium that are crucial as nuclear fuels.
