It is important for chemists to study changes in the world at a submicroscopic level because it allows society to better understand the interactions of how things work. For instance, actions that occur at the submicroscopic level can greatly affect our health. Chemical reactions also occur because of what is going on at the submicroscopic level. In order to better understand what is going on at the macroscopic level, we need to genuinely understand what is going on in the submicroscopic level.
