Atomism is the thesis that everything is ultimately composed of atoms. Typically, this thesis is characterized by an axiom stating, more simply, that everything has atomic parts. In the talk I argue that the success of this standard characterization crucially depends both on how the notion of sum and composition are defined. In particular, I put forward a novel definition of mereological sum such that: (i) is not equivalent to extant definitions in the literature, provided no strong decomposition principle is assumed; (ii) can be used to claim that the standard characterization of atomism fails in that having atomic parts is not sufficient to be the sum of atoms; and (iii) delivers a purely mereological distinction between structured and unstructured wholes,  (iv) accounts for cases of hierarchical composition.
