Radioisotopes are unstable isotopes of chemical elements that undergo radioactive decay. Stable isotopes are very stable and do not undergo radioactive decay. Radioisotopes are very unstable and undergo radioactive decay to obtain a stable state. Presence of 114 protons makes an isotope a stable isotope.Mar 11, 2018

What is the difference between radioactive and nonradioactive isotopes?

Answer. A nonradioactive isotope has a regular balance of protons, neutrons and electrons. An isotope becomes radioactive if it has too many neutrons, which causes the isotope to become unstable.

Are Stable isotopes are radioactive?

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.

What is the difference between a stable and unstable isotopes?

Stable isotopes are naturally occurring forms of elements that are non-radioactive. Unstable isotopes are atoms having unstable nuclei. Therefore, these elements undergo radioactivity. This is the main difference between stable and unstable isotopes.

What is the difference between a stable isotope and a radioisotope quizlet?

Stable isotopes are not radioactive nor dangerous. Unstable isotopes are radioactive and have a different mass number of the element.

What is difference between radioactive and radioactivity?

What is the difference between radioactivity and radiation? Radiation is the energy or particles that are released during radioactive decay. The radioactivity of a material refers to the rate at which it emits radiation.

What is difference between radioactive substance and radioactivity?

Radiation in the form of radiant particles or rays, is the result of a nuclear disintegration. Radioactive materials are atoms that have stored energy and may disintegrate in the future, releasing radiation.

What is meant by stable isotope?

Stable isotopes are elements with the same number of protons but different number of neutrons. Carbon exists as two stable isotopes: 12C, which has six electrons, six protons, and six neutrons, and 13C, which has six electrons, six protons, and seven neutrons.

Why are some isotopes radioactive?

These are radioactive isotopes, since they have an unstable atomic nucleus (due to the balance between neutrons and protons) and emit energy and particles when it changes to a more stable form. The energy liberated in the form change can be measured with a Geiger counter or with photographic film.

What’s the difference between stable and unstable?

Often a person with angina has pain that sets in after a predictable amount of exertion. This is stable angina. Unstable angina happens when the angina worsens.
