Detailed explanation-1: -A Mineral is defined as an inorganic, naturally occurring, homogenous solid, with a definite chemical composition, and ordered (crystalline) atomic structures.
Detailed explanation-2: -In geology, the classic definition of a mineral is: 1) naturally occurring, 2) inorganic, 3) solid at room temperature, 4) regular crystal structure, and 5) defined chemical composition. Some natural substances technically should not be considered minerals, but are included by exception.
Detailed explanation-3: -The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to identify a mineral is by examining its crystal form (external shape).
Detailed explanation-4: -Hardness. The ability to resist being scratched-or hardness-is one of the most useful properties for identifying minerals. Luster. Luster is how a mineral reflects light. Color. One of the most obvious properties of a mineral is color. Streak. Specific Gravity.
