Occurrence, isolation & synthesis

Bluish-white, lustrous metal [7].


In nature, zinc is found in the Earth's crust, 200 ppm, in minerals such as smithsonite/zinc spar, sphalerite/zinc blende, zincite, willemite, franklinite and gahnite [7]. The isotopes found in nature are 64Zn (48.89 %, stable), 66Zn (27.81 %, stable), 67Zn (4.11%, stable), 68Zn (18.57 %, stable) and 70Zn (0.62 %, stable) [7].

In pure solid form, zinc exist in a hexagonal close-packed crystal structure [2].
