Draw the Lewis structure of H2O. Include any nonbonding electron pairs. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

The total number of valence electrons is eight in the lewis structure of H2O i. e. water molecule.

One electron each from the two hydrogen atoms and six electrons from the oxygen atom. The two bonds are formed between two hydrogen and oxygen atom. This is shown in the figure below.
