WebRadioactive isotopes can also be used to study soil characteristics, such as the uptake and utilisation of essential nutrients by plants. What role do isotopes play in the food industry? To increase agricultural yield, radioisotopes were used to … WebIntroduction to Isotopes: Isotopes are atoms of the same element that have the same number of protons in their nucleus but a different number of neutrons. This results in isotopes having different atomic masses. Isotopes can be either stable or unstable, depending on the ratio of protons to neutrons in their nuclei. The discovery of
