Naming Ionic Compounds

3:35 Ionic Compounds and Formulae

Previous Limitations of Model Diagrams Next Properties of Ionic Compounds
  • Ionic compounds are formed from metals and non-metals.
  • Table salt is an example of an ionic compound, composed of positive sodium ions and negative chloride ions, with the formula NaCl.
  • Naming ionic compounds involves specific rules:
  • If composed of two elements, the name ends in "ide."
  • The metal's name remains unchanged, and "ide" replaces the non-metal's ending.
  • Example: NaCl is named sodium chloride.
  • For compounds with three elements, including oxygen, the name ends in "ate."
  • Example: CaSO4 is named calcium sulfate.
  • Example: Na2CO3 is named sodium carbonate.
  • Compounds with a hydroxide ion (OH-) end in "hydroxide."
  • Example: KOH is named potassium hydroxide.
  • The metal's name remains unchanged in all cases.
  • Recognizing the hydroxide ion is crucial for correct naming.
