How do you label a polar bond of a water molecule?

A polar bond in a water molecule (H₂O) is labeled by indicating the partial positive charge (δ+) on the hydrogen atoms and the partial negative charge (δ-) on the oxygen atom. This occurs because oxygen is more electronegative than hydrogen, causing it to attract the shared electrons more strongly. The resulting dipole moment reflects the unequal sharing of electrons, making water a polar molecule. The bond can be represented with an arrow pointing toward the oxygen atom, indicating the direction of electron density.
