So, Equestria has a periodic table… With only 9 columns, counting transition metals. They seem to have group 1 and 2, and are missing 3 groups from group III up. They certainly have the noble gases. Possible that they're missing a group 1 element?
Those symbols are interesting. Perhaps denoting the chemicals involved in certain forms of magic? I doubt that hearts are that relevant to Helium and Beryllium otherwise…
