Abstract
Chemistry and physics are so closely related that for many philosophers it hardly seems possible that chemistry should be emergent in any ontologically serious way. Firstly, chemistry itself individuates substances by their microstructural properties, at least from the point of view of chemistry. Secondly, during the twentieth century chemistry and physics worked closely together to provide physical explanations of the structure and bonding of molecules. In this paper I argue that each of these facts is fully consistent with the existence of strongly emergent chemical properties.
