CHEMICAL FORMULA IGCSE CHEMISTRY EDEXCEL {9-1}

RESOURCE CONTAINS BACKGROUND THEORY ON NAMING COMPOUNDS USING METAL AND NON METAL REACTIONS , EXTENDING TO NAMING COMPOUNDS WHEN OXYGEN AND ONE OTHER NON-METAL ATOM IS PRESENT AND REACTING WITH THE METAL TO FORM THE COMPOUND. THE RESOURCE THEN COVERS THE BACKGROUND THEORY OF WORKING OUT THE CHEMICAL FORMULA OF IONIC COMPOUNDS USING THE BALANCE CHARGE METHOD.
THE METHOD IS SIMPLIFIED IN A STEP BY STEP PROCESS YET EXTENDED SUFFICIENTLY TO COVER THE ENTIRE RANGE OF ABILITIES IN THE CLASS WITH STUDENTS GIVEN SAMPLE PROBLEMS TO COMPLETE ON ALL THE TOPICS COVERED.

i HAVE INCLUDED A SUMMARY SHEET OF ALL THE CATION AND ANION CHARGES NEEDED FOR IGCSE CHEMISTRY INCLUDING POLYATOMIC IONS. I HAVE ALSO INCLUDED ANSWERS TO THE PROBLEMS SET ON A SEPARATE SHEET

THE RESOURCES CAN BE USED FOR WHOLE OR PART LESSONS, REVIEWS TO CONSOLIDATE KNOWLEDGE AND UNDERSTANDING OF THE TOPICS OR AS TOPIC TESTS. THE RESOURCES ARE DESIGNED TO BE DIFFERENTIATED TO EXTEND ALL ABILITIES WITHIN THE CLASSROOM ON A CHALLENGING CONCEPT.

THE RESOURCES ARE DESIGNED FOR EDEXCEL IGCSE CHEMISTRY , BUT CAN BE ADAPTED WITH MINIMUM MODIFICATION TO USE FOR CAMBRIDGE, AQA OR OTHER IGCSE OR GCSE CHEMISTRY EXAM BOARDS.
