This PowerPoint resource provides a comprehensive lesson on representing alpha, beta, and gamma decay using nuclear equations. It is tailored for middle and high school physics classes focused on radioactivity and nuclear processes.

Key learning objectives:

• Representing alpha decay using nuclear equations, where the atomic number decreases by 2 and the mass number decreases by 4.
• Representing beta decay using nuclear equations, where the atomic number increases by 1 while the mass number remains unchanged.
• Understanding gamma decay as the emission of surplus energy without changing the atom’s structure or forming a new element.

Resource features:
The lesson begins with a starter activity to review foundational knowledge, such as the properties of radiation and the differences between irradiation and contamination. Students explore the components of alpha, beta, and gamma radiation, including their composition, penetration power, and ionizing effects.

Key topics include:

• Alpha Decay: Students learn to write equations for alpha decay, using examples like the decay of radon-222 into polonium-218. Visual aids and practice problems guide them in balancing nuclear equations.
• Beta Decay: The process of neutron-to-proton conversion is explained, emphasizing changes in the atomic number and the emission of a beta particle. Worked examples include the decay of nitrogen-14.
• Gamma Decay: Students understand that gamma radiation involves energy release without changing the atomic structure, distinguishing it from alpha and beta decay.

Interactive tasks challenge students to complete nuclear equations for various isotopes, apply periodic table knowledge, and analyze decay scenarios. Discussions on the stability of nuclei and decay sequences provide deeper insight into radioactive processes.
