Comparison of Bond Types

Nonpolar Covalent

A ^__B

   ·      Equal sharing
·      Nonelectrical
·      Same or similar electronegativity

Polar Covalent

  X^d+__   Y^d-

   ·      Two sided bond - a dipole
·      Somewhat Electrical 
·      Unequal sharing
·      Electronegativities are a little different

Ionic Bond

 J⁺   L^-

   ·      Transfer of Electrons
·      Very Electrical
·      Very Different Electronegativity
