Cubic zirconia (zirconium oxide) is a synthetic gemstone.

We also included information like melting and boiling points, heat of fusion and vaporization, electronegativity, electron configurations and much more. We accomplished this by grouping this information on one side of each element box. Teachers asked for a periodic table where the most vital information-atomic number, atomic symbol, name and atomic mass-doesn’t get lost. We asked the country’s best high school chemistry teachers, “What do you want in a periodic table?” We took their suggestions and incorporated them into Flinn’s new two-sided, four-color periodic table.
