The type of bond that holds the water molecule together is the polar covalent bond. In water (H2O), oxygen atoms share electrons with hydrogen atoms, leading to an unequal distribution of charge due to oxygen's higher electronegativity. This polarity results in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. The polar nature of water molecules also allows for hydrogen bonding between water molecules, contributing to its unique properties such as high specific heat and surface tension.
