A blog covering and explaining the Edexcel IGCSE Chemistry specification for the 2016 summer exams. If you are doing just double science, you do not need to learn the stuff for paper two, if you are doing triple you will need to learn all (GOOD LUCK!) I have separated the papers to make files easier to find. Hope it helps :)

Compounds with ionic bonding always have giant ionic structures, the ions are held closely together by the attraction between oppositely charged ions in a 3-D lattice arrangement.
