Rayner Canham table

But I conclude with a less controversial proposal. Let us imagine that the various representations of the periodic system he on a continuum. At one end of thk continuum is the unruly Rayner Canham table (figure 10.14) that attempts to do justice to many unusual relationships of the kind that have been highhghted in this chapter. At the other end of the continuum hes what I call the Platonic periodic table, or what is usually called the left-step or Janet periodic table (figure 10.13). Somewhere near the middle of thk continuum of representations, one can locate the currently popular medium-long representation. It is not altogether surprising that thk fbrm has been so popular since it appears to capture the correct...

Meanwhile, as mentioned above, the metallurgist Habashi has proposed a periodic table in which the element aluminum k moved to the top of the scandium group. Moving to chemists, Rayner Canham has published an Inorganic Chemist s Table (see figure 10.12), in which he highlights a number of unusual relationships, several of which have been reviewed in thk chapter. One particularly unusual feature of his table is the inclusion of the ions CN and NH/ because of their similarities to certain elements.
