Polarity_Of_Water

Polarity Of Water Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons. Oxygen also has two unshared pairs of electrons. Thus there are 4 pairs of electrons surrounding the oxygen atom, two pairs involved in covalent bonds with hydrogen, and two unshared pairs on the opposite side of the oxygen atom. Oxygen is an "electronegative" or electron "loving" atom compared with hydrogen. Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near hydrogen, water, oxygen, atom, pairs, two, electrons, bonds, unshared, unique, properties, due, partial, one, non-polar, near, molecules, molecule, hydrophobic, high, heat, electron, effect, compounds, atoms, via, vaporization, universal, uneven, together, thus, tension, surrounding, surface, structure
