Question

what are the physical and chemical properties of minerals?

Answer 1

Answer:

Color, luster, streak, hardness, cleavage, fracture, and crystal form are the most useful physical properties for identifying most minerals. Other properties-such as reaction with acid, magnetism, specific gravity, tenacity, taste, odor, feel, and presence of striations-are helpful in identifying certain minerals

Answer 2

Physical Properties:

1. Hardness : The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. Hardness is determined by the ability of one mineral to scratch another.
2. Luster : Luster is how a mineral reflects light. The terms metallic and nonmetallic describe the basic types of luster.
3. Color : One of the most obvious properties of a mineral is color. Color should be considered when identifying a mineral, but should never be used as the major identifying characteristic.

Chemical Properties:

1. Chemical Composition : Minerals can be made of just one element such as copper or be a combination of several elements in a chemical compound.
2. Cleavage : This relates to the number, direction and intensity of development of regular-spaced breakage directions of a mineral parallel to crystallographic planes. It reflects differing strengths of atomic bonding in different directions in the internal atomic structure.
3. Tenacity : This is the toughness of a mineral. It is the way in which a mineral is mechanically deformed.
