A map of the electronic structures of 54 unknown chemical elements that may lie beyond element 118, ununoctium, in the Periodic Table has been published by Pekka Pyykkö of the University of Helsinki, Finland. Computational methods suggest that elements up to atomic number 172 might be synthesized given sufficiently extreme conditions. The extra 54 super heavy elements predicted by Pyykkö will most likely have very short lifetimes due to radioactive decay. The work demonstrates how quantum mechanics and relativity function in determining chemical properties, explains Pyykkö, and allows theoretical Dirac-Fock calculations to predict the groups for these "new" elements.
