Electronegativity

• The pull an atom has on the bonding electrons within a covalent bond
• Nitrogen, oxygen, and fluorine have the greatest electronegativity
• The difference in the values of electronegativity determine the nature of bonding.

  Difference (0)= non-polar

  Large difference=ionic bonding

  Small difference= polar covalent bonding
• The atom with the larger value of electronegativity is delta minus
