An advanced (graduate) textbook that covers the reactivity of the elements.  A great descriptive chemistry resource.  The chapters are divided by element (for example, a chapter on H, a chapter on He) and some elements are grouped (for example, As, Sb and Bi).  Coverage includes natural occurence, isotopes, binary compounds, coordination compounds, organometallic compounds, characterization methods, synthetic methods.

In general, a readable book, and an excellent resource for problems in the realm of descriptive chemistry.
