WebBoron’s chemistry is as much defined by what it isn’t – carbon, or a metal – as by what it is. Recent years have started to fix this misconception, as James Mitchell Crow reports The periodic table is a symphony of straight lines, of rigid rows and careful columns of precisely positioned elements.
