Normal elements whose abbreviation letters are used entirely in the word creation.
This is a fictional element. I've added a couple of these because the letter Q doesn't exist in the Periodic Table. I also added Tritium
into this category because they're not elements but isotropes
This colour corresponds to an "impure" match to the supplied word. The match works only if you ignore the smaller letter in the element abbreviation.

In 2012 Tony Davis and I created a board game based on the Periodicals called Elemensus.
