Explanation:

Water (H2O) is made of Hydrogen and Oxygen. Valency of Hydrogen is 1, and valency of Oxygen is 2. Therefore, to balance the valency of Oxygen atom, 2 atoms of Hydrogen atoms are required. Hence, 2 atoms of Hydrogen will combine with 1 atom of Oxygen to form one molecule of water with the chemical formula H2O.
