How are physical properties of minerals useful?
The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties.
What are the 7 physical properties of minerals?
Among the properties we will discuss are: crystal habit, cleavage, hardness, density, luster, streak, color, tenacity, magnetism, and taste.
What are two important mineral properties?
A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical properties such as cleavage and hardness.
What are the physical properties of the rock forming mineral of your choice?
Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.

What are the common rock-forming minerals using their physical and chemical properties?
The chemical properties of minerals depend on their chemical formula and crystal structure. Solubility and melting point are chemical properties commonly used to describe a mineral. The most common rock-forming minerals are quartz, feldspar, mica, pyroxene, amphibole, and olivine.
Which physical property is the least helpful in identifying minerals?
-Streak is the least useful property for identification, as the same mineral type can be found with several different colors of streak due to impurities in the mineral.
