Atoms are considered to be the building blocks in nature. All of the materials, solid, liquid, or gas, with which we have daily experience are made up of atoms, by interactions between and among atoms. Chemical reactions involve changing partners among the atoms. This is not to say that atoms are the smallest of particles, or to say they cannot be subdivided. Rather, it states only that our daily experience involves changes between or among atoms, but does not involve subdivision of the atoms.
