This sample is naturally occurring, inorganic, solid, has a square crystal structure, and a definite chemical composition (NaCl)
Alika [10]

Answer:

A Mineral is defined as an inorganic, naturally occurring, homogenoussolid, with a definite chemical composition, and ordered (crystalline) atomic structures.

Explanation:

Inorganic: Involving neither organic life nor the products created from or by organic life.

Naturally Occurring: Must be formed by natural processes, meaning a mineral cannot be manmade, manufactured, or created in a laboratory.

Homogeneous Solid: A mineral must be chemically and physically uniform down to the atomic level.

This homogeneity means that the mineral will have absolutely predictable physical properties

including hardness, density, and streak.

Definite Chemical Composition means that all occurrences of that mineral have a chemical

composition that varies within a specific limited range and the atoms that make up the mineral must

occur in specific ratios.

Ordered Atomic structure (Crystalline): The atoms in a mineral are arranged in a systematic and

repeating pattern. Glasses such as obsidian, which are disordered solids, liquids (e.g., water,

mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.
