Ions and Formulas
1 Groups 1&2 and 6&7 (in the periodic table) are most likely to form ions
1.1 Group 1&2 elements are metals and they lose electron to form positive ions
1.2 Group 6&7 elements are non-metals and they gain electrons to form negative ions
2 Any of the positive ions above can combine with any of the negative to form an ionic compound
3 Only element at opposite sides of the periodic table will form ionic compound
3.1 Where one of them becomes a positive ion and one becomes a negative ion
3.2 Look at charges to work out the formula of an ionic compound
4 Ionic compound are made up of a positive charged part and a negatively charged part. The overall charge of any compound is zero
5 So all the negative charges in the compound must balance all the positive charges
