How the chemical properties of zircon help in determining the age of the earth | Britannica

SOLVED: 5. On the basis of crystal structure, compute the theoretical density for Zirconium Oxide (ZrO2) seen below. The red large spheres represent oxygen anions and the green small spheres represent zirconium cations. Zirconium dioxide exists as a monoclinic structure at room temperature (a = 5.80 Ã…, b = 4.84 Ã…, c = 5.01 Ã…), a tetragonal structure at a higher temperature (a = 5.14 Ã…, c = 5.19 Ã…), and a cubic structure at an even higher temperature (a = 5.17 Ã…). How do these values compar
