Lesson Title: Today we are learning about
How does nuclear radiation change an atom?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Nuclear equations are used to represent radioactive decay. (diagram)
  2. In a nuclear equation an alpha particle may be represented by the symbol:The symbol of an alpha particle.
  3. The symbol of a beta particle.
  4. The emission of the different types of nuclear radiation may cause a change in the mass and /or the charge of the nucleus.
  5. alpha decay causes both the mass and charge of the nucleus to decrease.
  6. Beta decay does not cause the mass of the nucleus to change but does cause the charge of the nucleus to increase.
  7. Students should be able to use the names and symbols of common nuclei and particles to write balanced equations that show single alpha (α) and beta (β) decay. This is limited to balancing the atomic numbers and mass numbers. The identification of daughter elements from such decays is not required.
  8. The emission of a gamma ray does not cause the mass or the charge of the nucleus to change.

Keywords:
  • Alpha: a helium nucleus emitted by some radioactive substances, originally regarded as a ray. (1)
  • Emission: the production and discharge of something, especially gas or radiation. (1)
  • Gamma: penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. (1)
  • Beta: a fast-moving electron emitted by radioactive decay of substances. (1)

AFL/Key Questions:
  1. How can nuclear equations be used?
    Nuclear equations are used to represent radioactive decay.
  2. What symbol represents an alpha particle?
    An alpha particle is represent by the following symbol: α
  3. What symbol represents a beta particle?
    An beta particle is represented by the following symbol: β
  4. What does the emission of the different types of nuclear radiation cause?
    The emission of the different types of nuclear radiation may cause a change in the mass and /or the charge of the nucleus.
  5. What does alpha decay cause?
    Alpha decay causes both the mass and charge of the nucleus to decrease.
  6. What does Beta decay cause?
    Beta decay does not cause the mass of the nucleus to change but does cause the charge of the nucleus to increase.
  7. How to balance alpha (α) and beta (β) decay equations?
    During alpha decay- A new element is formed that is two places lower in the Periodic Table than the original element. For example, radon decays into polonium when it emits an alpha particle. In beta decay, a neutron changes into a proton plus an electron. The proton stays in the nucleus. The electron leaves the atom with high energy as a beta particle. The nucleus has one more proton and one less neutron when it emits a beta particle. This means that: The atomic mass number stays the same The atomic number increases by 1
  8. What happens during the emission of a gamma ray?
    The emission of a gamma ray does not cause the mass or the charge of the nucleus to change.
