Naming Ionic Compounds
This page focuses on the systematic naming of iyonik yapılı bileşikler (ionic compounds). It outlines the general rules for naming simple and complex ionic compounds.
For simple ionic compounds:
- Name the cation (usually a metal) first
- Name the anion (usually a non-metal) second, often with an "-ide" ending
Example: AgCN is named silver cyanide
For compounds with polyatomic ions, the polyatomic ion name is used without change.
Example: CaCO3 is calcium carbonate
The page addresses naming compounds with metals that can have multiple oxidation states. In these cases, Roman numerals indicate the oxidation state of the metal.
Definition: Oxidation state refers to the degree of oxidation of an atom in a compound, represented by a positive or negative number.
Example: Fe2O3 is named iron(III) oxide
The concept of hydrates is introduced, where water molecules are incorporated into the crystal structure of an ionic compound. Naming hydrates involves specifying the number of water molecules using Greek prefixes.
Example: CuSO4·5H2O is copper(II) sulfate pentahydrate
The page concludes by briefly mentioning the crystal lattice structure of ionic compounds, where ions are arranged in a repeating three-dimensional pattern.
Highlight: The strong electrostatic forces between ions in a crystal lattice contribute to the high melting points of ionic compounds.
