Periodic Table Pen

Description

The most convenient reference guide available- the Periodic Table Pen. This pen is double-sided to depict a periodic table on the front, and a reference chart on the back for detailed study. The charts are colored-coded to distinguish between metals, non-metals, and noble gas families, and differentiate types of metals, solids, liquids, and gases from synthetic elements. Each also includes name, symbol, atomic number, weight, mass, and electron configuration for further detail. The pen is suitable for age 13 and older.
