Electronegativity and Polar Covalent Bonding - dummies

Electronegativity is the strength an atom has to attract a bonding pair of electrons to itself. When a chlorine atom covalently bonds to another chlorine atom, the shared electron pair is shared equally. The electron density that comprises the covalent bond is loed halfway between the two atoms. But what happens when the two atoms […]
