Binary Ionic Compounds

Nomenclature = the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals

We use a system of nomenclature chosen by IUPAC (IUPAC = International Union of Pure and Applied CHemistry

Binary = 2 different elements

Ionic = compounds with a metal and a non-metal

Valence = How many electrons needed to gain or lose to form a complete octet

In Binary Ionic Compounds

1. The metal or positive ion is always written first and the non-metal or negative ion is written second

2. The metal name is written as is and the non-metal ends in “ide”

eg.  sodium chloride = NaCl     the ions are Na1+ and Cl1-

Some binary compounds’ names will look like this:   sodium chloride

Others will have a roman numeral:            copper (II) chloride

Type I

Type II

Common Non-Metal (Negative) Charges

Type I: Binary Ionic Compounds (BIC)

Ionic compounds with metals with only one ion or monovalent metals. (Group IA, IIA, IIIA metals or Zn or Ag)

Naming Type I Binary Ionic Compounds

Check the periodic table and see which group the metals in the following compounds are in.  If they are in Group IA, IIA or IIIA of the periodic table or if they’re Ag or Zn, simply name the following compounds by writing the metal name and non-metal name ending in “ide”.

Type II: BICs

Ionic compounds with multivalent metals. (transition metals, Group IVA metals and Group VA metals)

multivalent =
