25 Oct 2009 Closer examination of the atoms that make up a given element has shown that, although they have the same number of protons, they can have differing numbers of neutrons. For example, the element carbon has three

The normal ones are carbon-12. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7, and 8 respectively. All industrial production of radioactive iodine isotopes involves these four useful radionuclides.

Carbon-12 is not an isotope because carbon has an atomic number of 12.

Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). The 138 La radioactive isotope constitutes 0.0902 % of naturally occurring lanthanum. The half-life (t 1/2) of this isotope is very long, 1.05 × 10 11 years. 138 La disintegration is due to two parallel processes.

Radioactive isotopes are …show more content… Because it describes organ function and not just structure, the information obtained during nuclear medicine methods is more inclusive than other techniques. These isotopes are radioactive in nature and are, therefore, known as radioisotopes (or radionuclides). Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238.

Isotope Definition and Examples in Chemistry. Isotope Examples. Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth's crust.

Sometimes isotopes decay from one unstable isotope into another unstable isotope. This can happen continuously in a long radioactive chain. An example of a radioactive chain is uranium-238. Radioactive isotopes have numerous medical applications in diagnosing and treating illness and diseases. One example of a diagnostic application is using radioactive iodine-131 to test for thyroid activity (Figure \(\PageIndex{1}\)).
