What is true about the atoms at the start of a chemical reaction compared to the atoms at the end of the reaction?

there is always the same number of atoms at start and end, no atoms 'disappear' and none are 'made'

In a chemical reaction, the atoms before and after the reaction are the same, meaning they are conserved. The law of conservation of mass states that matter cannot be created or destroyed, so the total number of each type of atom remains constant. Atoms are simply rearranged into new compounds with different properties without any loss or gain of matter.
