Question

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.

Answer 1

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.

Answer 2

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

Answer 3

i have no idea just copy the first guy
