21. Rules for Naming Ionic Compounds
Writing names
Show the charge of the transition metal with a Roman numeral. This can be determined by looking at the nonmetal.
Writing Formulas
Balance the compound by using the charge indicated by the roman numeral in the name.

27. Naming Molecular Compounds
Remember that binary molecular compounds are substances that consist of just two different elements.
Nomenclature:
1) Name the first element that appears in the formula.
2) Name the second element that appears in the formula, changing its ending to –ide.

28. Naming Molecular Compounds
Greek prefixes are used to denote the number of atoms of each element present.

29. The prefix mono- is generally omitted for the first element.
Naming Molecular Compounds
The prefix mono- is generally omitted for the first element.
For ease of pronunciation, we usually eliminate the last letter of a prefix that ends in “o” or “a” when naming an oxide.
Example: N2O5 is dinitrogen pentoxide not dinitrogen pentaoxide
