1. Nomenclature Advanced
Names for Type II Binary Ionic Compounds
Some elemental ions have different forms. For example, there are several forms of iron, copper, lead.
For the most part, you use the same naming mechanism as for Type I Binary Ionic Compounds.
However, you must indicate which elemental form you are using by adding a Roman numeral within parenthesis in between the two names.
Ex: chromium(III) chloride
Choose which element to use based on what will produce a zero overall charge.

2. Nomenclature Advanced
Names for Type III Binary Compounds
For non-metal elements, here are the rules:
1. The first full name of the element in the formula is named first.
2. The second element is named with an added “-ide” at the end
3. Prefixes are used to denote numbers of atoms present. See below.
4. The prefix mono- is never used for the first element.
mono- 1 penta- 5
di- 2 hexa- 6
tri- 3 hepta- 7
tetra- 4 octa- 8

3. check the ending of the name
