electronegativity

• Electronegativity is the ability of an atom to attract a bonding pair of electrons from a covalent bond.
• The factors which determine how electronegative an element are:

  • The nuclear charge
  • The atomic radius
  • The shielding
• Electronegativity increases as:

  • The nuclear charge increases
  • The atomic radius decreases
  • The shielding decreases
