    Study Notes

    Physical Properties of Minerals

    • Streak, luster, color, cleavage, fracture, and hardness are physical properties used to identify minerals.

    Atomic Structure

    • Protons are located in the nucleus of an atom.

    Mineral Properties and Uses

    • Corundum is a mineral commonly used for sandpaper and jewelry.

    Diamond and Graphite

    • The difference in hardness between diamond and graphite is due to the different arrangements of carbon atoms.

    Mineral Groups

    • Native elements are a mineral group made up of minerals containing only one element.

    Physical Properties and Mineral Identification

    • Streak can be used to identify the mineral composition.
    • Luster can be used to identify the mineral's appearance.
    • Color can be used to identify the mineral's visible appearance.
    • Cleavage can be used to identify the mineral's breaking pattern.
    • Fracture can be used to identify the mineral's breaking pattern when it does not cleave.
    • Hardness can be used to identify the mineral's resistance to scratching.

    Mineral Uses

    • Corundum is primarily used for sandpaper and jewelry.
    • Diamond is primarily used for drilling and cutting tools.

    Subatomic Particles

    • Protons are positively charged and located in the nucleus.
    • Neutrons are neutral and located in the nucleus.
    • Electrons are negatively charged and located in the electron cloud.

    Mineral Groups and Composition

    • Native elements are composed of minerals containing only one element.
    • Oxides are composed of minerals containing oxygen and one or more other elements.
    • Silicates are composed of minerals containing silicon and oxygen, along with other elements.
