 * Note that the group 12 elements are considered post-transition metals on the English Wikipedia by default. About half of the sources consider them as such with the other half considering them transition metals, but since even the latter half has to keep justifying that they lack the chemical and physical properties of the transition metals proper, the former has been chosen as the default as it is more chemically justified. The elements past Hs (except Cn) have not been coloured in as their chemistry is as yet experimentally unexplored. Double sharp (talk) 05:33, 28 November 2018 (UTC)
