Name ____________________________________Date______________________________Period________ Writing and Naming Binary Ionic Compounds Use the ion chart to complete part 1 1a) Naming Cations Na+ Ca+2 Cu+2 Al+3 K+ Fe+3 Was the name of the cation different than the element? If so, how? ________________________________________________________________________________________ __________________ How are Cu+2 and Fe +3 different from the other ions ? Why ________________________________________________________________________________________ _______________ 1b) Naming Anions S 2- F- N3- O-2 Cl- P3- Was the name of the cation different than the element? If so, how? ________________________________________________________________________________________ __________________ 1c) Since ionic compounds are written by balancing charges, the name does not reflect the amount of atoms in the molecule. Use the ion chart to help name the following compounds. Compound formula Cation name Anion name Compound name Ex. CaCl2 Ca = calcium Cl = chloride Calcium chloride NaF Na= F= Al2O3 Al= O= CuS ( hint cu is +2) Cu= S= Ag2O Ag= O= K3P BaCl2 Fe2O3 (hint Fe is +3) ZnBr2 Li3P BeSe PbO ( hint Pb has +2) SrF2 GaN CsI  CdF2 Part 2:Use the ion chart to help complete the writing of binary ionic compounds As discussed in the last lesson, ionic compounds should have a net charge of ZERO. 2A) Use the match maker interactive to practice creating balanced ionic compound formulas. Complete the following compounds by making balanced formulas. https://interactivechemistry.org/Matchmaker/ Name Cation Anion Complete formula Sodium chloride Sodium Oxide Sodium Nitride Magnesium Oxide Magnesium Chloride Aluminum Chloride Aluminum Oxide Copper (II) Bromide Magnesium Nitride Potassium Bromide Ferric Chloride Normally multivalent ions are specified using the charge. Write a better name for Ferric Chloride Ferric chloride could be called ___________________ chloride because the charge on the Fe is _______. 1b) Now write the formulas using the ion chart. Remember to reduce the value when possible and then crisscross. ( Hints on reducing: If the numerals are the same cancel; if they are different but both are even divide by 2) Formula Name Cation Anion Can I reduce Formula Ex: Copper (II) Oxide Cu+2 O2- Yes cancel CuO Ex: Lead (IV) Sulfide Pb+4 2 S-21 Yes divide by 2 Pb2 S = PbS2 Ex: Aluminum Oxide Al3+ O2- No Al3 O2 = Al2O3 Sodium Chloride Calcium Nitride Iron (III) Phosphide Lithium Oxide Aluminum Arsenide Strontium Carbide Silver Chloride Silver Oxide Magnesium Phosphide Potassium Selenide
