Oxygen can be shown by the structure that is red in the model.
The two hydrogen atoms in a water molecule make an angle of about 104.5 degrees. The bending form results from the repulsion between the lone pairs of electrons in the oxygen atom. Water's molecular shape gives it remarkable solvent properties, a high heat capacity, and the ability to form hydrogen bonds.
Because the oxygen atom is more electronegative than the hydrogen atom, the electron density is distributed unevenly. The oxygen atom receives a partial negative charge as a result, while the hydrogen atom receives a partial positive charge.
