If you're talking about in an actual sample, you'd need more data like how many moles you have of the reactant or product.

Just in terms of the equation : there are two from the water in the reactant (left) side, and one from the sodium hydroxide and two for the hydrogen gas on the product (right) side, so 2+1+2=5 atoms of hydrogen.
