‘Consequently, the more electronegative atom has a partial negative charge.’ ‘For example, electrons in a covalent bond are assigned to the more electronegative atom.’ ‘The less electronegative atom will have a partial positive charge since the shared electrons spend less time near it.’. There are numerous definitions of electronegativity. The commonly used measure of the electronegativities of chemical elements is the electronegativity scale derived by Linus Pauling in 1932. In it the elements are tabulated in decreasing order of electronegativity, fluorine being the most electronegative and cesium the least.

  1. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
  2. Arbitrarily, Pauling assigned a value of 4 for fluorine which is the most electronegative element. It must be born in mind that a particular numerical value given to the element does not represent the actual content of negative charge on it but it is the electron attracting tendency relative to the reference value.
