Naming Molecular Compounds

  1. 1. Naming Molecular Compounds<br />
  2. 2. Molecular compounds<br />Made of just nonmetals<br />Smallest piece is a molecule<br />Can’t be held together because of opposite charges.<br />Can’t use charges to figure out how many of each atom<br />
  3. 3. Easier<br />Ionic compounds use charges to determine how many of each.<br />Have to figure out charges.<br />Have to figure out numbers.<br />Molecular compounds name tells you the number of atoms.<br />Uses prefixes to tell you the number<br />
  4. 4. Prefixes<br />1 mono-<br />2 di-<br />3 tri-<br />4 tetra-<br />5 penta-<br />6 hexa-<br />7 hepta-<br />8 octa- <br />
  5. 5. Prefixes<br />9 nona-<br />10 deca-<br />To write the name write two words<br />
  6. 6. Prefixes<br />9 nona-<br />10 deca-<br />To write the name write two words<br />Prefix<br />name<br />Prefix<br />name<br />-ide<br />
  7. 7. Prefixes<br />9 nona-<br />10 deca-<br />To write the name write two words <br />One exception is we don’t write mono- if there is only one of the first element.<br />Prefix<br />name<br />Prefix<br />name<br />-ide<br />
  8. 8. Prefixes<br />9 nona-<br />10 deca-<br />To write the name write two words <br />One exception is we don’t write mono- if there is only one of the first element.<br />No double vowels when writing names<br />Prefix<br />name<br />Prefix<br />name<br />-ide<br />
  9. 9. Name These<br />N2O<br />NO2<br />Cl2O7<br />CBr4<br />CO2<br />BaCl2<br />
  10. 10. Write formulas for these<br />diphosphorus pentoxide<br />tetraiodine nonoxide<br />sulfur hexaflouride<br />nitrogen trioxide<br />Carbon tetrahydride<br />phosphorus trifluoride<br />aluminum chloride<br />
