Introdcution to atomic number, mass number and isotopes
Use a video micro-lecture that introduces the concepts of atomic number, mass number, and isotopes.
- Revise the components of an atom.
- Play the micro-lecture (video), "Atomic number, mass number, and isotopes", that introduces the concepts of atomic number, mass number, and isotopes.
- The video will help you to understand the definitions of the terms through examples of hydrogen, carbon, and uranium isotopes.
- For a more detailed exploration of isotopes, atomic mass, and methods to calculate the average atomic mass, you may use the PhET simulation tool and associated activity listed in the Additional Resources section of this lesson plan.
- This activity will help to calculate the average atomic mass of sample mixtures of isotopes by using various methods.
