Naming type i binary compounds
Naming Type I Binary Compounds

  • Binary compound

    • Made up of 2 elements consisting of a cation and an anion to make a Binary Ionic Compound

  • Made of a metal and non-metal element


Rules for naming type i ionic compounds
Rules for Naming Type I Ionic Compounds

  • 1. The cation is always named first and the anion second

  • 2. A simple cation (obtained from a single atom) takes its name from the name of the element. For example: Na+ is called sodium in the name of compounds containing this ion

  • 3. A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding –ide. Thus the Cl- ion is called Chloride

  • 4. Write the name for the compound by combining the names of the ions


Table 1 common simple cations and anions
Table 1: Common Simple Cations and Anions



Type ii naming binary ionic compounds that contain metals that form more than one type of cations
Type II – Naming Binary Ionic Compounds that contain metals that form more than one type of cations

  • This type of compound contains a metal that can form more than one type of cation (Transition metals)

  • Differs from the Type I in that you place the Roman Numeral in the name

  • The Roman numeral tells the charge on the ion, not the number of ions present in the compound


Examples1
Examples metals that form more than one type of

  • CuCl

    • Cu(I) chloride

  • HgO

    • Mercury (II) oxide


Type iii naming binary compounds that contain only nonmetals
Type III – Naming binary compounds that contain only nonmetals

  • 1. The first element in the formula is named first, and the full element name is used

  • 2. The element is named as though it were an anion

  • 3. Prefixes are used to denote the numbers of atoms present. These prefixes are given in the following table

  • 4. The prefix mono- is never used for naming the first element.

    • For example: CO is called carbon monoxide, not monocarbon monoxide



Examples2
Examples nonmetals

  • NO

    • Nitrogen monoxide

  • N2O5

    • Di nitrogen pentaoxide

  • SF6

    • Sulfur hexafluoride

  • SO2

    • Sulfur dioxide

  • P4O6

    • Tetra phosphorus hexaoxide


Review
Review nonmetals

  • Type I

    • Ionic compounds with metals that always form a cation with the same charge

  • Type II

    • Ionic compounds with metals (usually transition metals) that form cations with various charges

  • Type III

    • Compounds that contain only nonmetals
