Question

1.in zns crystal zn2+ ions occupy----------------void
2.give diffrences between crystalline and amorphous solid

Answer 1

In the given question we have to find the void in Zn2+ crystal and next we have to show the difference between Crystalline and Amorphous solids

Zn2+ occupies alternate tetrahedral voids.

For answer 2

Crystalline solids

In this type of solids the constituent particles of matter are arranged and organized in a specific manner.

These solids contain crystals in their structure and each crystal has definite geometry.

crystalline solids have low potential energy, they are the most stable form of solids.

Almost all solids fall in the category of crystalline solids including metallic elements (iron, silver, and copper) and non-metallic elements (Phosphorus, Sulphur, and iodine).

compounds like sodium chloride, zinc sulphide and naphthalene build crystalline solids.

Amorphous Solids

In this type of  solids  the constituent particles of matter are arranged in a random manner .

It is a non-crystalline solid with no proper arrangement of atoms in the solid lattice.

 Most solids are amorphous in nature

common examples of amorphous solids is glass, which is used widely in the manufacturing sector.

Hope understand this.

Thanks.
