  1. 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. Binary Ionic compounds

  4. Ionic Compound Definitions Ionic bond- bond formed by attraction between + and - ions Binary Ionic Compound- compound containing two elements—one metal and one non-metal + Cation - Anion

  5. Metals & Non-Metals Ionic Bonds are between metals & non-metals

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

  7. Example #1 NaCl

  8. Example #1 “Sodium” Cation NaCl Anion “Chlorine” becomes “Chloride” Sodium Chloride

  9. Example #2 CaBr2

  10. Example #2 “Calcium” Cation CaBr2 Anion “Bromine” becomes “Bromide” Calcium Bromide

  11. Example #3 K2O

  12. Example #3 “Potassium” Cation K2O Anion “Oxygen” becomes “Oxide” Potassium Oxide

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

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

  15. Binary Ionic CompundsName to Formula

  16. Ionic Compound Definitions Ionic bond- bond formed by attraction between + and - ions Binary Ionic Compound- compound containing two elements—one metal and one non-metal + Cation - Anion

  17. Metals & Non-Metals Ionic Bonds are between metals & non-metals

  18. Identifying & Naming Binary Ionic • These compounds: • End in “-ide” (except “hydroxide and cyanide”) • Do NOT contain covalent prefixes • To write these formulas: • Write the symbol & charge of the first element (the metal, cation) • Write the symbol & charge of the second element (the non-metal, anion) • Add more of the cations and/or anions to have a neutral compound • Use subscripts to show how many of each type of ion is there.

  19. Example #1 Sodium chloride

  20. Example #1 Na+1 Cation Sodium chloride Anion Cl-1 NaCl

  21. Example #1 Na+1 Cation Na+1Cl-1 Sodium chloride +1 + -1 = 0 Anion The compound is neutral…no subscripts are needed. Cl-1 NaCl

  22. Example #2 Calcium bromide

  23. Example #2 Ca+2 Cation Calcium bromide Anion Br-1

  24. Example #2 Ca+2 Cation Ca+2Br-1 Calcium bromide +2 + -1 = +1 Anion Ca+2Br-1Br-1 Br-1 +2 + -1 + -1 = 0 CaBr2 The subscript “2” is used to show that 2 anions are needed.

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

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