Question

2. The data in the table show the amount of a 500 g sample of sodium-24 over time.

Make a graph of the data (remember to label all axes and title the graph).
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

Hi, and welcome to QuestionCove!

For the graph, you can take the data from the table and plot the mass of the sodium remaining on the y-axis and the time that has passed on the x-axis, since the mass of the sample depends on the amount of time that has passed
The half-life of a substance is the amount of time it takes for the mass of the sample to decay into half of the original, right? So, in this case we start with 500g of sodium, and half of that is 250g. Find out at what time the remaining sodium is 250g, and that's the half-life

I don't really know about nuclear equations or beta-emission. You might have to do a bit of research to answer that one...
