Respuesta :
A radioactive isotope's proportion that endures over time. T can be determined by adding one-half to the elapsed time and dividing it by the half-life. Therefore, if 10 years have gone, the percentage that is left is equal to 1/2. the 10 raised, divided by The carbon 14 half-life is 5730 years, or.9988.
Why is an isotope radioactive?
Due to the equilibrium between neutrons and protons in their atomic nuclei, these are radioactive isotopes, and when their unstable atomic nucleus transforms into a more stable form, it emits energy and particles. A Geiger counter or photographic film can be used to measure the energy released during the shift in form.
What is radioactive isotope?
A radionuclide is an unstable nuclide with too much nuclear energy. The extra energy can either be transferred to one of the nucleus' electrons to release it as a conversion electron, released from the nucleus as gamma radiation, or used to build and emit a new particle from the nucleus.
