What is the function of sodium-24?
Sodium 24 is used as an electrolyte tracer to follow the path sodium takes in a person’s body to see if their uptake levels are within normal ranges, while sodium 22 is used in nuclear medicine imaging for positron emission tomography. Sodium -24 can also be used in non-medical applications.
Is sodium-24 stable?
Sodium-24 is a stable isotope containing 11 neutrons. Only trace amounts of sodium-24 are found naturally. Sodium-24 is a radioactive isotope which decays into 24Mg by β- decay. Its half-life is 14.96 hours.
What element is formed by the beta decay of sodium-24?
magnesium-24
With a half-life of 15 hours, it decays by beta decay to an excited magnesium-24 (24Mg) nucleus.
What are 4 properties of sodium?
Physical Properties of Sodium
| Atomic number | 11 | |
|---|---|---|
| Thermal conductivity (liquid) | 550°C | 0.648 W/cm-°C |
| b.p. | 0.486 W/cm-°C | |

| m.p. | 0.515 cal/g-°C |
What type of particle does sodium-24 emit when it radioactively decays?
beta decay
Sodium-24 undergoes beta decay, or, more specifically, beta-minus decay. During a beta decay, a neutron located in the nucleus of a radioactive nuclide is converted to a proton. At the same time, the nuclide emits an electron, also called a beta particle, and an electron antineutrino, ¯νe .
What is the adverse effect of sodium-24?
In some people, sodium might increase blood pressure. However, sodium is POSSIBLY UNSAFE when taken in doses greater than 2.3 grams daily. Larger doses might cause too much sodium to build up in the body. This might cause serious side effects including high blood pressure and heart disease.
What is the difference between sodium-23 and sodium 24?
The atoms of both isotopes contain 11 protons, but sodium-23 has 12 neutrons whereas sodium-24 has 13. Sodium-23 is quite stable (for example, it is one of the elements in common salt – NaCl, sodium chloride). Sodium-24, however, is not stable.
How does sodium 24 detect leaks?
Sodium 24 is an example of a radioisotope used in leak detection. It has a half life of about 15 hours and emits beta radiation and gamma radiation. Radioactivity can be used to date rocks. This is unstable and eventually decays to lead, which is stable.
What type of decay is sodium-24?
Sodium-24, a radioactive isotope used medically in blood studies, decays by beta decay and has a half-life of 15.0 hours.
What are the chemical properties of sodium element?
What is Sodium – Chemical Properties of Sodium – Symbol Na Element Sodium Atomic Number 11 Symbol Na Element Category Alkali Metal Phase at STP Solid
What is the molecular formula for sodium 24?
Sodium-24 Molecular Formula 24Na Average mass 23.991 Da Monoisotopic mass 23.990963 Da
What is the half life of sodium 24?
In sodium: Nuclear properties 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.…
What are the physical properties of sodium oxide?
Sodium is a silvery-white metal with a waxy appearance. It is soft enough to be cut with a knife. The surface is bright and shiny when first cut, but quickly becomes dull as sodium reacts with oxygen in the air. A thin film of sodium oxide (Na 2 O) forms that hides the metal itself.
