  1. Lesson 3.08 Ionic Bonding and Writing Formulas

  2. Common Anion Name Changes Watch the following video on naming ionic compounds in the main group then write the correct name for each anion using the steps shown in the video. • Nitrogen  • Phosphorus  • Oxygen  • Sulfur  • Selenium  • Fluorine  • Chlorine  • Bromine  • Iodine  http://bit.ly/VL5pLe

  3. Ionic Compounds #1 – Binary Naming Practice Write the correct name for each element. • MgCl2 • Al2N3 • KBr

  4. Ionic Compounds #2: Naming with Polyatomic Ions Watch the video about naming compounds with polyatomic ions In them. Polyatomic Ions:A group of atoms that are covalently bonded together and work as one ‘family’ with a charge. http://bit.ly/WY2xfS If the formula has 3 or more elements, you have a polyatomic ion. Circle all of the polyatomic ions present. Al(NO2)3NaClNaOH CrF3 (NH4)2S BaCl2 KClO3 AlF3 Download a copy of the polyatomic ion chart here: http://bit.ly/ZiVM2R

  5. Ionic Compounds #2: Naming with Polyatomic Ions Steps for naming compounds with polyatomic ions Example: Name NaOH • If the metal is a “main-group” metal. Name it. • Sodium • B. Name the polyatomic ion. • Hydroxide • C. Write the full name • Sodium hydroxide

  6. Ionic Compounds #2 – Polyatomic Naming Practice Writethe correct name for each of the compounds below • MgClO3 • Al(NO3)3 • KCN

  7. Ionic Compounds #3 – “Special” Metal Naming Practice Watch the following video for help with naming “special” metals: • CuClO3 • ZnS2 • Pb3N4 • CuSO4 http://bit.ly/13nFg8I

  8. Ionic Naming Flowchart – Copy & Save in Your Notebook http://bit.ly/10mdzfT

  9. All Together Now – Ionic Compound Naming Practice • CuSO4 • FeS2 • CaCO3 • V2O5 • NH4Cl • SnO2

  10. Number of atoms of each element How many atoms of oxygen are in one formula unit? Draw a line to the correct number: • Li2O • Al(NO3)3 • (NH4)3PO4 • CuCr2O7 One Two Four Six Seven Eight Nine

  11. ALL Ionic Compounds – Comprehension Check • How many atoms of oxygen are in one formula unit of Ca(NO3)2? • What is the name of PbCl2? • If the formula for a compound is represented by XY3 and the charge on the Yion is -1, what is the charge in the Xion? • Which of the following contains ionic bonding? • P2O5 b. CaCl2 c. CO2 • Which of the following contains both ionic and covalent bonding? • NaNO3 b. SO4 c. CO2 • Which of the following is not a name of a valid chemical formula? • Ammonium nitrate b. Magnesium (II) sulfide • What is the formula for iron (II) nitride?

  12. Covalent Naming – Binary compounds Please watch the following video for help with naming Covalent compounds: Covalent bonds happen between? Highlight one. a). Metal and non-metal b). Two Non-metals c). Two Metals Put a check by the statements that are true: • Covalent bonds do have ions. • Covalent bonds do not have ions. • Covalent bonds do have charges. • Covalent bonds do not have charges. http://bit.ly/12yfrDB

  13. Covalent Naming Prefixes – Print & Put in Your Notebook Click here to download the covalent naming prefixes chart http://bit.ly/YF5AX7

  14. Covalent Naming Practice Write in themissing information into the blanks. • SiO­2 Silicon ___ oxide 2. BBr3 boron ____ bromide 3. dinitrogenmonoxide N__O 4. tetraphosphorustriselenide P___Se___

  15. Naming Acids – Two Types Take a look at the following video to see how to name binary and oxyacids: http://bit.ly/YHnpVH Drag a line from the acid to the correct category. N2O NO HNO3 H2CO3 P2O5 H3PO4 Binary Acids Oxyacids

  16. Acids #1 – Naming OxyacidsPractice • H2CO3 • H3PO4 • Acetic acid • Hypochlorous acid

  17. Acids #2 – Naming Binary Acids Practice • H2S • HCl • Hydronitric acid • Hydrobromic acid

  18. Naming Acids Flowchart http://bit.ly/YHsb5r

  19. All Acid Naming Practice • H2S • H2SO3 • H2SO4 • Chloric acid • Chlorous acid • Hypochlorous acid

  20. Thank You! • It has been great working with you for naming and writing formulas for ionic and covalent compounds! You will use this for the rest of module 3, module 4 and most of segment 2. • Please use our other recorded teaching sessions for the other lessons. Don’t forget that you can use them to review previous lessons too!
