Reactivity of polonium
WebIn the presence of silver metal, any polonium in solution will react with the silver to produce the very stable silver polonide. The equation for this reaction is: (5.10) and the Gibbs energy for the reaction is −158.2 kJ mol −1 (equivalent to a reaction stability constant of log K =27.7, thus demonstrating the high stability). WebOct 19, 2024 · Polonium is a rare but highly radioactive element that is found naturally in the atmosphere and on the earth’s crust in very small quantities. In its natural state, polonium is solid, silver-colored metal. Purified polonium is volatile, but polonium isotopes are radioactive. Polonium has about 25 known radioactive isotopes.
