We demonstrate a network-inspired approach for treating atomic spectroscopy data of hydrogen, helium and iron. Nodes of the network represent states, while links represent transitions between them. We find that the node community structure coincides with state labels derived from the quantum mechanical treatment of atoms. Using state-of-the-art methods for link prediction we are able to predict unknown atomic transitions.
