The majority of elements on the Periodic Table are able to mingle with other, thereby forming molecules, mixtures, compounds, and new substances. Some elements, however, are "unreactive" and don't mix easily with other elements. In this latter category fall the Noble Gases, so-called because they show an almost aristocratic reserve, standing at a remove from other elements. Readers will learn that while aloof, the noble gases have many practical uses including in lasers, blimps, hot air balloons, colorful illuminated signage, incandescent light bulbs, fluorescent lights, arc welding, window insulation, flash bulbs, strobe lights, and cancer treatment.
This is the second book I have read in this series, and it suffers by comparison with the first one I read. I suppose that this could be because the noble gases aren't nearly as interesting as lithium! Nonetheless, I learned a few things, and by no means am I going to give up on this series.
