  1. What’s in a name? • When two people use different names for the same thing, misunderstood words are apt to happen. The British and Americans often get confused.

  2. American English American English British English British English Find the bonnet. Find the boot.

  3. Which is the chemist and which is the pharmacist? In Ireland and England, the people who Americans call pharmacists are called chemists

  4. British English American English Where's the dummy?

  5. Plaster: American English Plaster: British English Which is plaster and which is a band-aid?

  6. Kerosene vs. Paraffin Kerosene: American English Paraffin: British English Paraffin: American English

  7. Nomenclature • A System of Naming Compounds • Compounds are two or more atoms of different elements bonded together. • Even though the gases O2, N2, F2, and Cl2 travel in pairs, their names are simply oxygen, nitrogen, fluorine, and chlorine.

  8. METALS vs. Non-METALS

  9. NOMENCLATURE NON-METAL BINARY COMPOUNDS

  10. Toxic Gases F2 & Cl2 (Fluorine & chlorine gas) HF(g)Hydrogen Fluoride HCl(g)Hydrogen Chloride H2S Dihydrogen Sulfide HCN – Hydrogen cyanide NO - NO2- NO3 - N2O Cl2O dichlorine monoxide NH3 Ammonia PCl3Phosphorus trichloride

  11. "GREEDY" with their electrons "GENEROUS" NON-METALS METALS

  12. NOMENCLATURE OF COVALENT COMPOUNDS WITH 2 ELEMENTS BINARY

  13. In order to be effective in using prefixes to name compounds containing two non-metals, these prefixes must be committed to memory: mono- 1 hepta- 7 di- 2 octa- 8 tri- 3 nona- 9 tetra- 4 deca- 10 penta- 5 undeca- 11 hexa- 6 dodeca- 12

  14. Example #1-Names to Formulas I’m a Binary Compound Sulfur trioxide 1. Write symbols of elements S O 1 3 2. Write number of atoms If no prefix, then 1 is implied and not written Final Formula

  15. Example #2-Names to Formulas I’m a Binary Compound dichlorineheptaoxide 1. Write symbols of elements Cl O 2 7 2. Write number of atoms Final Formula

  17. Example #4-Names to Formulas I’m a Binary Compound dinitrogentetraoxide 1. Write symbols of elements N O 2 4 2. Write number of atoms Final Formula

  18. Example #5-Names to Formulas I’m a Binary Compound phosphorus pentachloride 1. Write symbols of elements P Cl 5 1 2. Write number of atoms If no prefix, then 1 is implied and not written Final Formula

  19. Example #6-Names to Formulas I’m a Binary Compound dinitrogen monoxide 1. Write symbols of elements N O 1 2 2. Write number of atoms If no prefix, then 1 is implied and not written Final Formula

  20. Example #7-Names to Formulas I’m a Binary Compound carbon monoxide 1. Write symbols of elements O C 1 1 2. Write number of atoms If no prefix, then 1 is implied and not written Final Formula
