Summary How to proper name a compound and acid in chemistry

Chapter 5

Nomenclature – Naming compound
- Binary compounds (composed of two elements)
o Type 1 – Metal present forms only one cation
o Type 2 – Metal that have two charge (transition ions)
o Type 3 – only contain non-metals
- Polyatomic compounds
- Acids
- Organic compounds / other

Rules for naming Type 1 Ionic compounds
- Cation is always named first and the anion second
- A simple cation takes its name from the name of the element
- A simple anion is need by taking first part of the element
name and adding “-ide”

Rules for naming Type 2 Ionic compounds
- Metals here can form more than one type of cation
- Charge on the metal ion must be specified
- Roman numeral indicated the charge of the metal cation
- Transition metal cations usually require a Roman numeral




Rules for naming Type 3 ionic compounds
- The first element in the formula is named first and
the full element name is used
- The second element is named as though it were an
anion
- Prefixes are used to denote the numbers of atoms
present
- The prefix “mono-“ is never used for naming the first
elements
