What is the half-life of sodium-24?
Sodium-24 has a half-life of 15 hours. How much sodium-24 will remain in an 18.0 g sample after 60 hours? Sodium-24 has a half-life of 15 hours. How much sodium-24 will remain in an 18.0 g sample after 60 hours?
What is the radioactive decay of sodium 24?
radioactive decay of sodium-24 Figure 7: Decay scheme of a radioactive sodium-24 (24 Na) nucleus. With a half-life of 15 hours, it decays by beta decay to an excited magnesium-24 (24 Mg) nucleus. Two gamma rays are rapidly emitted and the excitation energy is carried off, whereby the stable ground state of magnesium-24 is reached.
What is the half life of magnesium 24?
Two gamma rays are rapidly emitted and the excitation energy is carried off, whereby the stable ground state of magnesium-24 is reached. Sodium-24 (15-hour half-life) is limited in use by its short life and is produced by irradiation in a nuclear reactor.
How is sodium 24 produced in a nuclear reactor?
Encyclopædia Britannica, Inc. Sodium-24 (15-hour half-life) is limited in use by its short life and is produced by irradiation in a nuclear reactor. Because of this reaction, a sodium-cooled reactor must have a second heat-transfer loop so that radioactive sodium does not come in contact with the environment.…
