The atoms of the reactants are regrouped during the reaction.
The atoms of the reactants are regrouped during the reaction.

Atoms of Na are destroyed during the reaction.
Atoms of Na are destroyed during the reaction.

There are more H atoms after the reaction.
There are more H atoms after the reaction.

Some atoms gain mass after the reaction.

Answer 1

The atoms of the reactants are regrouped during the reaction.

(Atoms are conserved and simply rearranged to form the products; no atoms are destroyed or gain mass, and the number of H atoms stays the same.)
