The objectives are to:
* recall the structure of an atom in terms of the positions, relative masses and relative charges of subatomic particles
* recall what is meant by the terms atomic number and mass number
* Define the terms isotopes and relative atomic mass (Ar)
* Calculate the relative atomic mass of an element (Ar) from isotopic abundances.
It includes practice for calculating Ar and an edexcel exam question. I have included the video from fuseschool which I have used in this lesson.
PPT focuses on electronic configuration with teacher led presentation. Students can then complete the electronic configuration for first 20 elements.
It's good to leave some feedback.
