Respuesta :
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.

The structure of water has 2 atoms of Hydrogen and 1 atom of oxygen.
The hydrogen atom has 1 valence electron and oxygen has 6 valence electrons. The bonding of 2 hydrogens will result in the 2 pair of loan pair to the oxygen atom.
The bonding electrons in the water molecule are 4, 2 of hydrogen and 2 of oxygen. 4 Non-bonding electrons or 2 loan pairs are present in the molecule of water.
The lewis structure for the water is represented in the image attached.
