Electronegativity is, in essence, how strongly an atom will pull a pair of electrons towards itself in a covalent bond. Electronegativity will have a significant impact on the behaviour of covalent molecules by affecting the polarity of the overall molecule. Bonds between atoms of significantly different electronegativities will be significantly more polar than those between atoms of similar electronegativities. Electronegativity can be measured using the Pauling scale.
