Ionic Compounds

Key Concepts:




Learning Objectives:

  • Ionic nomenclature

  • Writing Binary Formulas

  • Naming Binary Compounds

  • Naming Non-Binary Compounds

  • Naming Ionic Compounds

  • Writing Ionic Compounds



Ionic compounds are formed by combining a metal with a non-metal like:

  • CaO

  • FeCL3

  • CusN2


  • metals lose electrons to become positive ions, non-metals gain eectrons ti becime negative ions

  • when an ionic bond is formed, the charge must be balanced



practice questions:

  • how are ionic compounds form?

  • how were ionic compounds discovered?

  • what are ionnic bonds? how are they formed?




Steps to Naming Binary Compounds

  1. Write the name of the metal first

  2. Add the Roman Numeral of the metal’s charge after the metal (ONLY IF: the metal has 2 different charges)

  3. Change the ending of the non-metal into -ide



Examples:

Na3P → Sodium Phosphide

VF5 → Vanadium (V) Fluoride

Cu3N2 → Copper (II) Nitride
