Types of Isotopes & Their Uses ... For example, in geochemistry, scientists study the chemical composition of geological materials such as minerals and rocks. Stable isotopes are dependable tools for determining many facts about geological materials, such as their age and where they came from.


Examples of isotopes are O-16, O-17 and O-18. These isotopes can be used in forensics, but are even more accurate in their ability to tell whether a certain rock originated on Earth, Mars or even an asteroid. Oxygen isotopes can also tell how the oceans have been heating up or cooling down over eons.


Every chemical element has one or more radioactive isotopes. For example, hydrogen, the lightest element, has three isotopes, which have mass numbers 1, 2, and 3. Only hydrogen-3 , however, is a radioactive isotope; the other two are stable. More than 1,800 radioactive isotopes of the various elements are known.


Isotopes are important due to their uses. Examples include Carbon-14 for dating rocks, Iodine-131 for diagnosing thyroid problems, Cobalt-60 for medical radiotherapy and industrial radiography ...


In this lesson, we will learn all about radioactive isotopes and their uses. What Are Radioactive Isotopes? Before we go into discussing radioactive isotopes, let's recall what an isotope is.


I take the reference to “isotopes” to mean uses of nuclear reactions in daily life. 1. Every home should have smoke alarms. They use the isotope americium 241 to produce mostly alpha particles, which cooperatively don’t travel far, but instead ion...


For example, an isotope with 6 protons and 6 neutrons is carbon-12 or C-12. An isotope with 6 protons and 7 neutrons is carbon-13 or C-16. Note the mass number of two isotopes may be the same, even though they are different elements. For example, you could have carbon-14 and nitrogen-14.


Some Types of radioisotopes are Radioactive sodium carbon, phosphorous, Iodine, Gold. Radioisotopes examples. Examples of natural radioisotopes are 238 U (uranium), 40 K (potassium), 232 Th (thorium) and their child nuclei (obtained by radioactive decay of the previous ones) 226 Ra (radio), 222 Rn (radon) and 218 Po (polonium).


Examples of radiogenic isotopes include argon-40 and hydrogen-4. Lesson Summary The isotopes of an element are like different versions of an element - they have the same number of protons but ...


Radioactive isotopes may also be classified as stable isotopes when their half-lives are too long to be measured. These elements can often be found to occur in nature and include isotopes of carbon, nitrogen, hydrogen, oxygen, noble gases and metals. For example, there are a lot of carbon atoms in the universe. The normal ones are carbon-12.
