1f - ionic bonding

• Ionic Bonding

  Bonding where atoms are chemically joined together
• Valence electrons

  Outer shell electrons
• Ion

  A charged particle of an atom which has lost or gained valence electrons
• Period

  • Number of shells
• Group

  • Number of outer shell electrons
• Dot and Cross Diagram

  1. Identify number of outer shell electrons (each)

  2. Identify the electron transfer(s)

  3. Draw the ions
• Ionic Bond

  The electrostatic attraction between positively and negatively charged ions
• The number of positive and negative ions are equal to each other, and if not, find the lowest common denominator
• Ionic Structures

  • Uniform Lattice - 3D
  • Strong ionic bonds in between
  • Giant Structure (Infinite in Size)
• Stronger ionic bonds

  Higher boiling point, more energy to break bonds
• Weaker ionic bonds


  Lower boiling point
• Ionic compounds can be soluble or conduct electricity
