Atoms combine in whole number ratios to form compounds.

Atoms cannot be created or destroyed during a chemical reaction.

Explanation:

In a chemical reaction mass is conserved, mass cannot be created or destroyed. Thus atoms cannot be created or destroyed during a chemical reaction.

Atoms combine in whole number ratios to form compounds. For example, in CO₂, one atom of C combines with two atoms of O.  

Elements are made up of atoms and not the reverse.
