Folded Periodic and Formula Tables by Daisy Zhang-Negrerie

This unique periodic table is folded into three parts: main group, d-block transition metals, and f-block transition metals. As a result, all the groups are in one complete table, rather than artificially divided into different segments as in a traditional periodic table. On the back of the 60 cm wide space is included all the most fundamental formulas organized by topics, which is especially useful for the AP Chemistry students, serving as a efficient and compact study guide.
