Isotopes and Mass

- Tutorial - Examples - Quizzes - No Worksheets needed - Peer Marking - Foundation Level. This was made for my bottom set year 9 class who have just started their foundation GCSEs. They are really trying but much of this stuff is proving very difficult for them. This is therefore aimed at very low level learners to help them understand the meaning of isotopes first and foremost. There is also a little bit on Relative Atomic Mass and Relative Molecular Mass with calculation questions.
