**Q5: **

What is the relative charge of a beta particle?

**Q6: **

When an atomic nucleus emits a beta particle, how much does the mass number of the remaining nucleus change by?

**Q7: **

The graph shows an isotope of thallium undergoing beta decay. The number of protons of the isotope is shown on the -axis, and the number of neutrons of the isotope is shown on the -axis.

What isotope of thallium does the graph show?
