Bonding ? General Concepts Electronegativity: The ability of anatom in a molecule to attract shared electrons to itself. Ionic Bonds Electrons are transferred Electronegativity differences are generally greater than 1.7 The formation of ionic bonds is always exothermic! Determination of Ionic Character Compounds are ionic if they conduct electricity in their molten state Electronegativity difference is not the final determination of ionic character Coulomb?s Law ?The energy of interaction between a pair of ions is proportional to the product of their charges, divided by the distance between their centers? There will be a negative sign on the Energy once calculated?it indicates an attractive force so that the ion pair has lower energy than the separated ions.
