Worksheet: Beta Decay
In this worksheet, we will practice how to solve nuclear equations involving beta decay.
What is the relative charge of a beta particle?
When an atomic nucleus emits a beta particle, how much does the mass number of the remaining nucleus change by?
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?
What isotope does the thallium become?
|Number of Protons||81||82||83||84||85||86||87|
Bismuth can undergo beta decay. Which of the elements listed in the table does a bismuth nucleus become when it undergoes beta decay?
Which of the following statements correctly describes the process of beta decay?
- AIf an unstable nucleus has too many nucleons, 2 protons and 2 neutrons may be ejected from the nucleus.
- BIf an unstable nucleus has too many protons, a proton may decay into a neutron, releasing a high-energy electron from the nucleus.
- CIf an unstable nucleus has too many neutrons, one or more neutrons will be ejected from the nucleus.
- DIf an unstable nucleus has too many neutrons, a neutron may decay into a proton, releasing a high-energy electron from the nucleus.
Which of the following is the correct symbol for a beta particle?
The diagram shows beta decay of beryllium-10. What isotope is produced in this process?
