Every time I see a "periodic table of X elements" a question pops to my mind: what is the benefit of arranging elements totally unrelated to the natural ones using the same structure?<p>In the original table, elements are arranged in rows, columns and colors using their specific properties, which actually are not at all present in these html elements.<p>In this table I see only the meaning for the colors, but why not to use the two dimensions of the table to convey something different (losing, of course, the familiar shape)?
