• These study notes include physical and chemical properties-reactions, balanced equations, uses of elements and compounds

• A shortened version of this page which you can save to desktop or incorporate into a school website and all links should work OK? and find your syllabus, and use the revision list-links.

• Email me if you think anything is missing? AND say which GCSE syllabus and I MAY/MAY NOT? be able to add extra bits.

• PLEASE remember not all of the notes are needed by any student, but they have to cover ALL syllabuses and there is a link to a section of links to quizzes, worksheets, crosswords etc.

• Some of these web pages are very long BUT remember there is a sub-index at the top of every page and you can do 'highlighted-selected' printouts.
