In a balanced chemical equation, the number of atoms in the reactants is equal to the number of atoms in the products. This is due to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
For example, in the balanced chemical equation for the reaction of hydrogen and oxygen to form water:
\[ 2H_2 + O_2 \rightarrow 2H_2O \]
The number of atoms in the reactants (4 hydrogen atoms and 2 oxygen atoms) is equal to the number of atoms in the products (4 hydrogen atoms and 2 oxygen atoms).
If you're looking for a specific example, any balanced chemical reaction will satisfy this condition, such as:
\[ 2Na + Cl_2 \rightarrow 2NaCl \]
In this case, there are 2 sodium atoms and 2 chlorine atoms in both the reactants and products.
