Atoms of the same element with different numbers of neutrons are called isotopes. A: The nucleus may be unstable because it has too many protons or an unstable ratio of protons to neutrons. For a nucleus with a small number of protons to be stable, the ratio of protons to neutrons should be 1:1.
Q. What property of radioisotopes makes them useful?
What properties of radioactive isotopes make them useful? Radioactive isotopes give off energy that can be used to generate electricity all the radiation the isotopes five off allows them to be used as tracers in diagnosing and treating disease. The atomic mass of iron is 55.847 amu.

Q. What are two requirements of radioisotopes to make them useful?
A radioisotope used for diagnosis must emit gamma rays of sufficient energy to escape from the body and it must have a half-life short enough for it to decay away soon after imaging is completed.
Q. What property of radioisotopes makes them useful as radiotracers to follow the path of elements in reactions?
A radioactive tracer, radiotracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products …
Q. What causes an isotope to be radioactive?
Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus.
Q. How do you explain stable isotopes?
Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil management, environmental studies, nutrition assessment studies and forensics.
Q. What are some examples of common stable isotopes?
Commonly analysed stable isotopes include oxygen, carbon, nitrogen, hydrogen and sulfur. These isotope systems have been under investigation for many years in order to study processes of isotope fractionation in natural systems because they are relatively simple to measure.
Q. Why are some isotopes more stable than others?
Atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force, while protons repel each other via the electric force due to their positive charge. These two forces compete, leading to some combinations of neutrons and protons being more stable than others.
