A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms. Since electrons spend more time with the oxygen atom, it carries a partial negative charge.Another example of a polar covalent bond is between a hydrogen and chlorine atoms. In this bond, the chlorine atom spends more time with the electrons than the hydrogen atom.hey are not equally sharing the toys. This unequal sharing also happens with a type of bond called polar covalent bonding. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.
