... If the electrons are equally distributed (shared) along the bond axis then this type of bond is called NONPOLAR covalent bonds. A dipole moment can be used to visualize the polarity of the bond and is represented by an arrow pointing towards the more electronegative atom and a “+” on the tail. ...
