Isotopes can be either stable or unstable. Stable isotopes do not change over time, whereas unstable isotopes undergo radioactive decay, transforming into different elements or isotopes. This process can release particles or energy. For example, Carbon-12 is stable, while Carbon-14 is unstable and used for radiocarbon dating.

FAQs & Answers

  1. What makes an isotope stable or unstable? An isotope is considered stable if it does not undergo radioactive decay over time, while unstable isotopes are radioactive and transform into other elements or isotopes by releasing particles or energy.
  2. What are common examples of stable and unstable isotopes? Carbon-12 is an example of a stable isotope, whereas Carbon-14 is unstable and commonly used in radiocarbon dating.
  3. How do unstable isotopes decay? Unstable isotopes undergo radioactive decay, a process that transforms them into other elements or isotopes by emitting particles or energy.
  4. Why is Carbon-14 important in science? Carbon-14 is an unstable isotope used in radiocarbon dating to determine the age of archaeological and geological samples.
