A lesson plan from St. Ninian’s High School for N5 Chemistry students, focusing on Unit 3 – Chemistry in Society, specifically Part B – Fertilisers, Nuclear and Chemical Analysis, Lesson 2 – Types of Radiation. The lesson aims to help students revise nuclide notation and isotopes, identify and describe the three types of radiation, and understand their properties and penetration strength. Students are encouraged to read the notes, watch provided links, complete self-check questions, and submit homework.

By the end of this lesson you should:
1. Have completed a short revision of nuclide notation and isotopes. 2. Be able to identify and describe the three types of radiation. You will have been successful in this lesson if you: 1. Read, copy and learn the notes given 2. Watch the links provided 3. Complete and mark self-check questions 4. Complete and submit homework assigned There is also a further reading section to help you gain more depth of understanding for this section. If you have any questions about the content of this lesson, you should ask your class teacher either through your class MS team or via email. MS Teams will be monitored throughout the week by a chemistry teacher. If you need help or clarification with either the task or the content of the lesson, just ask.

4. Comparing , , and radiation: (a) Which has no electrical charge? (b) Which has the largest mass? (c) Write out the nuclide notation (symbol, atomic number, mass number and charge) to represent an alpha particle. (d) Which is not made up of particles? (e) Why are beta particles not like normal electrons? 5. A sheet of paper, a sheet of aluminium 5mm thick and a sheet of lead 2cm thick are placed in front of a Geiger Muller tube and connected to a counter. A stream of gamma rays, beta and alpha particles are directed towards the paper. (a) Which radiation(s) pass through the paper? (b) Which radiation passes through the aluminium?
