polar covalent bonds

A polar covalent bond occurs when two atoms share electrons, but the sharing is unequal. This happens because one atom attracts the electrons more strongly than the other, creating a charger imbalance within the molecule. As a result, the atom with the greater pull becomes slightly negative (having a higher electron density), while the other becomes slightly positive. This difference in charge distribution leads to a molecule with distinct regions of positive and negative charge, which influences how the molecule interacts with others. Examples include water, where oxygen is slightly negative and hydrogen is slightly positive.
