A polar covalent bond shares electrons unequally. Because of this unequal sharing, one end of the molecule is slightly positive, and the other end slightly negative. Edit
A covalent bond is the force of attraction between the opposite charges of the ions in an ionic compound? No, an ionic bond is when an electron/electrons are taken completely from one atom and moved to another. A covalent bond occurs when there is a sharing of electrons between atâ¦oms.
