The type of chemical bond found in a water molecule is a polar covalent bond. In a water molecule (H₂O), the oxygen atom shares electrons with two hydrogen atoms, but due to the higher electronegativity of oxygen, it attracts the shared electrons more strongly. This unequal sharing results in a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms, creating a dipole. The polar nature of water contributes to its unique properties, including its solvent capabilities and high heat capacity, making it vital for life.
