Isotopes and Relative Atomic Mass Calculations Lesson

Isotopes and Relative Atomic Mass Calculations

GCSE Chemistry 9-1 AQA (Specification 1.1.6)

1. Define what an isotope is

2. Describe examples of isotopes of elements

3. Calculate the relative atomic mass from isotopic abundances

This resource is a PowerPoint to support teaching about isotopes and how to conduct calculations to find the relative atomic mass given isotopic abundances.

Included in the resource:

• Opening slide with title, keywords, learning objectives and lead on topics
• Starter slide with simple intro task
• Information slides on isotopes, abundances and example calculation answers
• Question slides on calculating relative atomic mass for elements with multiple isotopes
• Plenary question slide to consolidate learning
