Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic. It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio. Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of Zn + S = ZnS, the equation is balanced.

The results of the chemical analyses of the sphalerites investigated are shown in Table 1, where the chemical formula was calculated on the basis of two atoms per formula unit (apfu). The sphalerite samples contained an extensive range of Mn (between 0 and 14.10 wt.%). Iron occurred in appreciable quantities and ranged from 0.05 wt.% to 9.48 wt.%. Since the number of atoms in a single unit cell of Zn and S is the same, it is consistent with the formula ZnS. The ionic radius for Zn 2+ is 74pm and …
