  • Ionic bonding involves:
    • Cations: positive ions formed when metal atoms lose electrons, having a net positive charge and a noble gas electronic configuration
    • Anions: negative ions formed when non-metal atoms gain electrons, having a net negative charge and a noble gas electronic configuration
  • Ions of opposite charges (+) and (-) can join by ionic bonding due to a mutual electrostatic force of attraction
  • Ionic compounds are neutral substances consisting of ions of opposite charges held together by electrostatic forces of attraction
  • In an ionic compound, the total positive charges from cations must equal the total negative charges of anions, resulting in no net charge
  • In the solid state, ionic compounds exist as a 3D giant lattice structure, forming a giant ionic crystal lattice of alternating positive and negative ions
