front 1 ionic bonding (2) | back 1 -occurs between nonmetal and metal -electrons are transferred from the metal to the nonmetal forming full outer shells |
front 2 binary compounds (3) | back 2 -contain only 2 elements e.g calcium chloride (CaCl2) -put the metal first, change the ending of the second element to -ide -Ionic lattice must be neutral so charges must be equal |
front 3 polyatomic ions (3) | back 3 -contain more than one atom NO3 - - nitrate, SO4 2- - sulphate, CO3 2- - carbonate, OH- - hydroxide, NH4 - - ammonium ions from the halogens are called halide ions |
