  1. Binary Ionic CompoundsFormula to Name

  2. The Language of Chemistry Chemistry has a language all of its own Chemistry English Element Symbols Letters Chemical Formulas Words Chemical Equations Sentences Each element symbol starts with a capital letter

  3. Ionic Compound Binary Ionic Compounds Ionic bond: bond formed by attraction between + and - ions + Cation - Anion

  4. Metals & Non-Metals Ionic Bonds occur between metals & non-metals

  5. Identifying/Naming: Binary Ionic Compounds • These compounds have: • 2 elements (“binary”) • A metal & a non-metal (“ionic”) • To name: • Name of the metal (the cation) • Name of the non-metal (the anion) with the suffix “-ide” The subscripts in the formula do not matter when naming this type

  6. Example #1 CaBr2

  7. Example #2 K2O

  8. Let’s Practice CaF2 Na3P NaI SrBr2 Example: Write the name for the following compounds

  9. Let’s Practice CaF2 Na3P NaCl SrBr2 Calcium fluoride Sodium phosphide Sodium chloride Strontium bromide Example: Write the name for the following compounds

  10. Binary Ionic CompoundsName to Formula

  11. Writing Formulas: Binary Ionic • These compounds: • End in “-ide” (except “hydroxide and cyanide”) • Do NOT contain covalent prefixes • To write: • Symbol & charge of the metal cation • Symbol & charge of the non-metal anion • Add more of the cations and/or anions until you have a neutral compound • Use subscripts to show how many of each type of ion you have

  12. Example Sodium fluoride

  13. Let’s Practice Cesium chloride Potassium oxide Calcium sulfide Lithium nitride Example: Write the following chemical formulas

  14. Let’s Practice Cesium chloride Potassium oxide Calcium sulfide Lithium nitride CsCl K2O CaS Li3N Example: Write the following chemical formulas

  15. Multivalent Ionic CompoundsFormula to Name

  16. Multivalent (Transition) Metals Multivalent Metal: a metal that has more than one possibility for cationic (positive) charge The Appendix of your book (Page A-2) has the following chart Common multivalent metals and their charges Cobalt Co+2 Co+3 Copper Cu+1 Cu+2 Iron Fe+2 Fe+3 Lead Pb+2 Pb+4 Manganese Mn+2 Mn+3 Mercury Hg2+2 Hg+2 Tin Sn+2 Sn+4

  17. Multivalent Metals: Formula to Name • To identify: • Have a transition metal • To name these compounds: • Name of the metal cation • Name of the anion • Determine total negative charge • Total negative charge must = total positive charge • Determine the charge on each metal atom • Write the charge in roman numerals in parenthesis after the metal’s name

  18. Example #8 CuCl2

  19. Example #9 Fe2(CO3)3

  20. Let’s Practice PbCl2 PbCl4 MnO Mn2O7 Example: Write the name for the following compounds

  21. Let’s Practice PbCl2 PbCl4 MnO Mn2O3 Lead (II) chloride Lead (IV) chloride Manganese (II) oxide Manganese (VII) oxide Example: Write the name for the following compounds

  22. Multivalent Ionic CompoundsName to Formula

  23. Multivalent Metals: Name to Formula • To identify: • Will have roman numerals • To write these formulas: • Same as binary • Roman numerals tell the charge of the metal cation

  24. Example #5 Iron (III) oxide

  25. Example #6 Copper (I) nitride

  26. Let’s Practice Iron (II) nitride Copper (I) chloride Lead (IV) sulfide Tin (II) oxide Example: Write the following chemical formulas

  27. Let’s Practice Iron (II) nitride Copper (I) chloride Lead (IV) sulfide Tin (II) oxide Fe3N2 CuCl PbS2 SnO Example: Write the following chemical formulas

  28. Polyatomic Ionic CompoundsFormula to Name

  29. Polyatomic Ions Polyatomic Ionic Compound - Polyatomic Anion Polyatomic Ion: more than one atom that together have a charge Polyatomic Ionic Compound: compound containing at least one polyatomic ion + Cation

  30. Help Identifying Polyatomic Ions • Only cation polyatomic ion: NH4 • All other polyatomic ions are anions (back-half) • Subscripts must match exactly as it appears on your list • If there are parenthesis, the polyatomic ion is inside

  31. Practice Identifying Polyatomic Ions NaNO3 NH4Cl Ca(OH)2 (NH4)3PO4 K2CO3 Example: Identify and name the polyatomic ion in each compound

  32. Practice Identifying Polyatomic Ions NaNO3 NH4Cl Ca(OH)2 (NH4)3PO4 K2CO3 Nitrate Ammonium Hydroxide Ammonium & phosphate Carbonate Example: Identify and name the polyatomic ion in each compound

  33. Polyatomic Ionic:Formula to Name • To identify: • More than 2 capital letters (not starting with H) • at least 1 metal & 1 non-metal • To name: • Name of the cation • If the anion is a polyatomic ion, write the polyatomic ion’s name just as it is • If the anion is a single non-metal element, use “-ide”

  34. Example #1 NaNO3

  35. Example #2 (NH4)2S

  36. Let’s Practice Ca(NO3)2 Na3PO4 NH4ClO K2CO3 Example: Write the name for the following compounds

  37. Polyatomic Ionic CompoundsName to Formula

  38. Polyatomic Ionic: Name to Formula • To identify: • Do not end with “-ide” (except hydroxide & cyanide) • Do not use covalent prefixes • To write these formulas: • Write the symbol & charge of the cation & anion • Add additional cations or anions to have a neutral compound • Use subscripts to show the number of ions • - When using subscripts with a polyatomic ion, you must put the polyatomic ion in parenthesis.

  39. Example #3 Sodium carbonate

  40. Example #4 Magnesium nitrate

  41. Let’s Practice Sodium nitrate Calcium chlorate Potassium sulfite Calcium hydroxide Example: Write the following chemical formulas

  42. Let’s Practice Sodium nitrate Calcium chlorate Potassium sulfite Calcium hydroxide NaNO3 Ca(ClO3)2 K2SO3 Ca(OH)2 Example: Write the following chemical formulas
