Why is Thorium Unstable? Unpacking Radioactivity and Decay

Discover why thorium is unstable and how alpha decay transforms it into more stable elements in our informative Q&A.

135 views

Thorium is unstable due to its large atomic number and radioactive nature. It undergoes alpha decay, where it emits alpha particles to transform into a slightly lighter, more stable element. This process continues through multiple decay chains until it reaches a stable form, making thorium inherently unstable.

FAQs & Answers

  1. What is thorium used for? Thorium is primarily used as a nuclear fuel in reactors and has potential applications in the production of clean energy.
  2. What is alpha decay? Alpha decay is a type of radioactive decay in which an unstable nucleus emits an alpha particle, consisting of two protons and two neutrons.
  3. How do radioactive elements decay? Radioactive elements decay through various processes, transforming into different elements or isotopes until they reach stability.
  4. Is thorium safe to handle? While thorium is radioactive, it poses a lower risk compared to other radioactive materials due to its low levels of radiation and longer half-life.
