Electronegativity - Is the ability an atom has to attract the electrons in a covelant bond

Electronegativity is affected by...

  • The number of protons in the nucleus 
  • The distance of the shared pair or electrons from the nucleus
  • The sheilding effect of full shells of electrons between the nucleus and shared pair

Across a period elecronegativity increases
Down a group elecronegativity decreases

The most elecronegative element is fluorine

Symetrical
