Isotopes – Meaning, Types, 5 Examples, Uses, and Facts About Isotopes
Table of Contents
The concept of isotopes has often confused many students, particularly when defining and distinguishing them from other elements. However, there’s no need to worry any longer.
This blog post will comprehensively explain isotopes, covering everything from their definition to their various applications. Read through it for a clear and thorough understanding of the topic.
What are Isotopes?
Isotopes refer to different forms of an element that possess varying numbers of neutrons. While all isotopes of an element share the same atomic number and number of protons, they exhibit distinct atomic masses. Although isotopes exhibit similar chemical properties, their nuclear properties differ.
Every element comprises isotopes; among the 81 elements with stable forms, a total of 275 isotopes exist. It is worth noting that elements with stable isotopes also possess radioactive isotopes, also known as radioisotopes.
Conversely, radioactive elements do not possess any stable isotopes. Scientists have identified over 800 radioactive isotopes, some occurring naturally and others exclusively produced in laboratories.
Types of Isotopes
here are the two types of isotopes
1. Stable Isotopes
Over time, these particular isotopes decay, transforming into either a different isotope or even a different element altogether. The majority of naturally occurring elements are composed of stable isotopes.
2. Unstable Isotopes
Radioisotopes, also known as radioactive isotopes, can emit radiation. The original isotope is referred to as the parent isotope during radioactive decay. In contrast, the atoms produced due to the decay are daughter isotopes.
Example of Isotopes
- Carbon 12
- Carbon 14
- Uranium 235
- Uranium 238
- Deuterium
Uses of Isotopes
here are the uses of isotopes
- Carbon-14, a carbon isotope, finds application in carbon dating, where measuring its quantity in fossils aids in determining their age.
- Isotopes of Uranium, like U-235, serve as a fossil fuel in nuclear reactors.
- Radioactive isotopes, such as detecting cancerous cells, are commonly employed in medical contexts.
- Iodine, as an isotope, is utilized in the treatment of goitre.
Facts About Isotopes
Here are the facts about isotopes
- Hydrogen stands as the only element with uniquely named isotopes.
- Among the elements, hydrogen has the fewest number of isotopes.
- Caesium and xenon hold the record for having the highest number of isotopes among the elements.
- All artificially created elements are radioactive isotopes.
- The reaction of isotopes from the same element varies, with heavier isotopes exhibiting slower reactivity than lighter isotopes of the same element.
- Twenty-six elements are classified as monoisotopic, possessing only one stable isotope.
- Iodine isotopes find application in treating goitre and the localization of brain and liver tumours.
- Cobalt-60 is the radioactive isotope utilized in cancer treatment.
