Sina Safari,Julian M. Londoño Monsalvee halogens, hydrogen, and oxygen are surveyed, permitting a large area of chemistry to be discussed without the burden of too many facts. The structural relationships in the elemental forms of the non-metals are then used as an introduction to the catenated compounds, including the boron hydrides. I
