  4. 4.  a bond is a force of attraction between two atoms  Ionic bond between atoms of metals and nonmetals   Bonds that are formed by transfer of electrons from one element to the other.  Produce charged ions all states. Conductors and have high melting point.  Examples; NaCl, CaCl2, K2O
  5. 5.  generally occurs in compounds of metals and non-metals .  It is the result of the attraction of oppositely charged ions.  The structures formed are very orderly and are given the name crystal lattice.  Ionic solids are called crystals.
  6. 6.  No sharing of electrons occurs between the ions in the crystal lattice.  As a result, ionic solids are brittle.  Ionic solids conduct electricity only in the molten state, and not very well.  Ionic solids are characterized by very high melting and boiling points.
  7. 7.    Ionic bonds are much stronger if the ions have a large charge. Ionic solids do not conduct electric current because the ions are held together in a rigid structure. Ionic substances that are dissolved in water are good conductors because the charged ions are free to move in the solution.
  8. 8.  Ionic bonds have an electronegativity difference between 1.7 and 3.3

  15. 15. Which ball represents the Na? 
  16. 16.  Atoms gain or lose electrons to arrive at a full set of valence electrons.  When atoms gain or lose electrons they become ions.  Ions are attracted to ions of opposite charge and repelled by ions of the same charge.   This type of bonding is called ionic bonding  Atoms become ionic by losing or gaining electrons from the atom it is bonding with
  17. 17. • The electrical force of attraction between oppositely charged ions. For Example: Na+ F−
