Question

The structure of $CuS{O}_4$ is in nature.

• A. amorphous
• B. crystalline
• C. flexible

Answer 1

The correct option is B crystalline

Crystalline structure refers to a fixed arrangement of the ions/ atoms/ molecules that make up a substance.

The smallest unit of a crystalline arrangement is known as "lattice". (It is comparable to the bricks, that when laid systematically, form a wall).

Some of the common crystalline structures are tetrahedral, hexagonal, rhombic, orthorhombic, etc. The structure of $CuS{O}_4$ is orthorhombic.

Amorphous structure on the other hand, means no systematic arrangement of the constituent particles, such as in coal, charcoal, coke, etc.
