Correct answer and explanation
Correct answer: Radioactivity
Explanation: The Curie is a unit used to measure radioactivity, representing the rate of radioactive decay. 📚 Other Information: ▪️ Named after Marie and Pierre Curie, pioneers in radioactivity. ▪️ 1 Curie (Ci) = 3.7 × 10¹⁰ disintegrations per second. ▪️ Modern SI unit: Becquerel (Bq) → 1 Bq = 1 disintegration per second. ▪️ Radioactivity is the spontaneous disintegration of unstable nuclei. ▪️ Common radioactive elements: Uranium, Radium, Thorium. ▪️ Used in nuclear medicine, radiotherapy, and isotope tracing. ▪️ Radioactive decay follows an exponential law and depends on half-life. ▪️ Measuring radioactivity helps in age dating (carbon-14) and cancer treatment.
