Which of the following is NOT one of the five major physical properties of minerals?

• A. Crystal form
• B. Density
• C. Chemical composition
• D. Magnetism

Answer: (C)

The five major physical properties of minerals typically include crystal form, density, hardness, color, and streak, among others. While chemical composition is crucial in identifying a mineral and understanding its properties, it is not classified as a physical property. Instead, it refers to the specific arrangement and types of elements within a mineral, which contributes to its overall characteristics but does not fall under the category of physical descriptions such as how a mineral looks or behaves in terms of density or crystal structure. Crystal form describes the geometric shape of a mineral's crystals, density measures how much mass is contained in a given volume, and magnetism refers to a mineral's ability to attract iron. Each of these plays a direct role in how a mineral is identified and classified based on observable and measurable traits. Therefore, while chemical composition is vital for a comprehensive understanding of minerals, it is distinct from the physical properties used for identification purposes.
