What is the half-life of sodium-24? Explain how you determined your answer.
Sodium-24 decays by beta emission. Write a nuclear equation that shows the decay of sodium-24 and
its products.
i have no idea just copy the first guy
number on left is atomic number.
number on right is mass number.
11Na24 ==> -1e0 + 12Mg24
You give no data to determine the remaining part of the question.
In high N divided by Z nuclei, neutrons decay into a proton with the release of a beta particle (beta emissions). The atomic number increases by 1, but mass remains the same
therefore,
11Na24 ==> -1e0 + 12Mg24
To determine the half-life of sodium-24, we need to find reliable sources such as scientific databases or research articles that provide the information. One such source is the National Nuclear Data Center, which is a comprehensive online database for nuclear information. By searching for "Sodium-24" in this database, we can find the half-life of this isotope.
The National Nuclear Data Center shows that the half-life of sodium-24 is approximately 15 hours. This means that after 15 hours, half of the sodium-24 atoms in a sample will have decayed into other elements.
Now, let's write the nuclear equation for the decay of sodium-24. Sodium-24 decays by beta emission, where a neutron in the nucleus of the sodium-24 atom is converted into a proton, releasing a beta particle (an electron) and an antineutrino. The resulting nucleus has one more proton than the original nucleus, therefore changing the element.
The nuclear equation for the decay of sodium-24 can be written as:
^24Na -> ^24Mg + eā» + š
Here, ^24Na represents sodium-24, ^24Mg represents magnesium-24, eā» represents the beta particle (electron), and š represents the antineutrino.
In summary, to find the half-life of sodium-24, we consulted reliable sources like the National Nuclear Data Center. We found that the half-life of sodium-24 is approximately 15 hours. Additionally, we wrote the nuclear equation for the decay of sodium-24, indicating that it decays into magnesium-24, a beta particle, and an antineutrino.
