Web16 nov. 2024 · The longest-lived isotope is curium-247 with a half-life of 15.6 million years. Man-made isotopes that are created in kilogram quantities are curium-242 (half-life: 163 days) and curium-244 (half-life: 18 years). Curium is the most radioactive element that can be isolated. Why is curium used in pacemakers? WebCurium compounds When curium is heated with fluorine at 400°C, the product is CmF4, a tetravalent curium compound. However, heating with other halogens yields trivalent halides, CmXa. Similarly, when heated with hydrogen chloride gas at 500°C, the product is curium(lll) chloride, CmCls. Solid curium compounds are known, e.g., CmF3, CmF4, …
