  1. Warm Up • Why do you think we need to name compounds? Ex. Strontium Chloride Carbon Dioxide Iron (II) Chloride

  2. Writing Formulas and Naming Compounds

  3. Binary Compounds • Binary compounds consist of two elements bonded together. • Ie. NaCl, KI

  4. Formulas (a Review) • Make the following compounds using either the Morgan or Jones way. Na + Cl Ca + F B + O

  5. Oxidation Numbers (a Review)

  6. Now that we made them, we got to name them. Rules for naming: • The element with the POSITIVE oxidation number goes first. (Just write the name, don’t change it at all) Na Cl SODIUM

  7. The element with the negative oxidation number goes second. • Na Cl • SODIUM CHLORINE

  8. Change the ending of the second element to “–ide” Name: Sodium Chloride! • Na Cl • SODIUM CHLORIDE

  9. Let’s try again Ca F2 Calcium Flourine

  10. Ca F2 Calcium Flouride Name: Calcium Fluoride

  11. One more… B2O3 Boron Oxygen

  12. One more… B2O3 Boron Oxide Name: Boron Oxide

  13. Some common endings

  14. Now some practice • Binary compounds will be placed on board. Write the correct formula, and name…

  15. WARM UP • Write the names of the following compounds… • Be + S • K + P • Ra + O • Ga + Br • Mg + N

  16. Charges on Transition elements • Where are the transition elements? Name a few.

  17. Charge of Trans. Elements. • Why didn’t we give the transition elements oxidation numbers? • They can have multiple charges. • So how do we know what charge they have?

  18. All in the name… • For those with more than one charge, the oxidation number (or charge) will be written in Roman numerals next to the elements name. The numerals will always be for the first element in the name. What’s the charge of each transition element in the following: • Copper (II) Chloride • Iron (III) Fluoride • Lead (IV) Oxide

  19. Same element, different charge Copper can have a +2 or a +1 charge, so depending on the formula, the name could be… • Copper (II) Chloride Copper (I) Chloride Iron can have a +3 or a +2 charge… • Iron (III) Fluoride Iron (II) Fluoride Lead can have a +4 or a +2 charge… • Lead (IV) Oxide Lead (II) Oxide

  20. With all of these charges, how do you know what’s what? Look to the formula… and the front board. Say you have the formula CuCl2 • What charge is always on Chlorine? -1. 2. How many Chlorines do we have? 2. 3. You have one Cu, so what charge has to be on Cu to cancel out that -2, and make the compound neutral? +2 4. What would it’s name be? Copper (II) Chloride

  21. Now… Look to the formula… and the front board. Say you have the formula CuCl 1. What charge is always on Chlorine? -1. 2. How many Chlorines do we have? 1. 3. You have one Cu, so what charge has to be on Cu to cancel out that -2, and make the compound neutral? +1 4. What would it’s name be? Copper (I) Chloride

  22. FeF3 1. What charge is always on Fluorine? -1. 2. How many Fluorinesdo we have? 3. 3. You have one Fe, so what charge has to be on Fe to cancel out that -3, and make the compound neutral? +3 4. What would it’s name be? Iron (III) Fluoride

  23. FeF2 1. What charge is always on Fluorine? -1. 2. How many Fluorines do we have? 2. 3. You have one Fe, so what charge has to be on Fe to cancel out that -2, and make the compound neutral? +2 4. What would it’s name be? Iron (II) Fluoride

  24. PbO2 1. What charge is always on Oxygen? -2. 2. How many Oxygensdo we have? 2. 3. You have one Pb, so what charge has to be on Pbto cancel out that -4, and make the compound neutral? +4 4. What would it’s name be? Lead (IV) Oxide

  25. PbO 1. What charge is always on Oxygen? -2. 2. How many Oxygens do we have? 1. 3. You have one Pb, so what charge has to be on Pb to cancel out that -2, and make the compound neutral? +2 4. What would it’s name be? Lead (II) Oxide

  26. ONLY TRANSITION METALS WILL HAVE A ROMAN NUMERAL!!!!

  27. Practice Write the names for the following 1. CrO • AuN • AuF3 • Cu2S • FeSe Write the formulas for the following • Manganese (II) Oxide • Nickel (III) Phosphide • Palladium (IV) Chloride
