What Is the Electron Pair Geometry of H2O?

The electron pair geometry of water, with the chemical formula H2O, is a tetrahedral. This structure gives a water molecule a bent molecular shape.

A molecule is the smallest fundamental unit of a pure chemical compound. It comprises two or several types of atoms. A water molecule is one of the most commonly occurring molecules in nature. It consists of two hydrogen atoms that are chemically bonded to a single oxygen atom.

A water molecule has two electron pairs and two bond pairs. In a molecule, the bond pairs and lone pairs are positioned in a manner that results in the least amount of repulsion between them, based on the valence shell electron pair repulsion, or VSEPR, theory. The tetrahedral electron pair geometry of a water molecule results in its angular form, where the bond angle between the atoms is 104.5 degrees.
