📝 Topic Summary – Radioactive Isotopes
• Radioactive isotopes have unstable nuclei that emit radiation.
• Example: ³H (Tritium) is radioactive, while other hydrogen isotopes are stable.
• Uranium-238 decays into Thorium-234 with energy emission.
• Bismuth-210 transforms into Thallium-206 through decay.
• Radioactive decay helps in nuclear reactions, medical imaging, and dating methods.
