I will start with the idea of electronic shell models as proposed for simple metal clusters, and show how this leads to the idea of superatoms. I will then present our work on 3d transition metal (TM) doped alkali and alkaline earth clusters and show how the ideas of electronic shell models play out in these. This will lead us to magnetic superatoms. I will also point out how a subtle interplay of crystal field effect and exchange coupling leads to enhanced stability for certain TM-alkaline earth clusters, and leads to new magnetic superatoms in this series. Time permitting, I will present some of our recent results on TM-doped aluminum clusters and will argue that aromaticity rather than shell models plays a role in these clusters.
