Isotopes of an element have the same atomic number.

We all know that a large number of elements exist as isotopes. The isotopes of an element have same atomic number but different mass numbers. The isotopes. With higher mass number are mostly radioactive in nature. These are called radioisotopes. These isotopes have a wide range of applications. (i) Which isotope is used to study the kinetics of photosynthesis ? (ii) Name the isotope which can detect a blood clot. (iii) Which isotope is used to detect the deformity in bones, if any ?
