Roughly, the size of an element�۪s own niche (���I almost wrote square�۝)

is proportioned to its abundance on Earth�۪s surface, and in addition,

certain chemical similarities (e.g., Be and Al, or B and Si) are suggested

colors suggested by the positioning of neighbors. The chart emphasizes that in

real life a chemist will probably meet 0, Si, Al, . . . and that he better

do something about it. Periodic tables based upon elemental abundance

would, of course, vary from planet to planet. . . W.F.S.
