Explanation:
Electronegativity is a measure of the tendency of an atom to attract electrons to itself. Atoms with high electronegativities attract electrons more strongly than atoms with low electronegativities. This difference in electronegativity can lead to the formation of polar and nonpolar covalent bonds.
A polar covalent bond is a covalent bond in which the electrons are shared unequally between the two atoms. This occurs when the atoms have different electronegativities. The atom with the higher electronegativity will attract the electrons more strongly, resulting in a partial negative charge on that atom and a partial positive charge on the other atom.
A nonpolar covalent bond is a covalent bond in which the electrons are shared equally between the two atoms. This occurs when the atoms have the same electronegativity. The electrons are not attracted to either atom more strongly than the other, resulting in no partial charges on either atom.
Electronegativity is a useful tool for predicting the type of bond that will form between two atoms. It can also be used to predict the shape of molecules
