Def of electronegativity
WebOct 26, 2015 · 2 Answers. Bond strength usually refers to the energy required to break a bond homolytically--with one electron going to one of the atoms and the other electron going to the other atom. In the case of HF this requires more energy than in CH4. Acidity is the tendency for the bond to break heterolytically--with two electrons going to one atom and ... WebThe meaning of ELECTRONEGATIVE is having a tendency to attract electrons.
