    Study Notes

    Classification of Matter Study Notes

    • An atom is the smallest unit of an element, indivisible by ordinary chemical processes.
    • A pure substance consists of only one type of particle, examples include elements and compounds.
    • Matter includes all physical substances that possess mass and occupy space.
    • Carbon (C) is a fundamental example of an element, representing a pure substance.
    • A mixture is represented by particle diagrams with different types of particles not chemically combined, such as Z where colors are touching but separate.
    • Pure substances exhibit consistent composition and properties throughout different samples.
    • A compound consists of atoms from two or more elements bonded chemically.
    • Perfume containing water, rose essence, and vanilla is categorized as a mixture due to its varied components.
    • All types of matter, living or not, comprise atoms as their basic units.
    • Vaporization is a process used to separate components of a homogeneous mixture, as seen when blue crystals remain after heating a pale blue liquid.
    • Solutions are classified as homogeneous mixtures where components are evenly distributed.
    • Pizza is an example of a heterogeneous mixture due to distinctly visible toppings.
    • Matter inherently possesses mass and volume as fundamental physical properties.
    • The particle diagram representing a compound shows different types of atoms/molecules combined.
    • Pure substances are not comprised of two different atom types but have a constant composition, which can be an element or a compound.
    • Mixtures, such as milk, can be physically separated into their individual components.
    • An element consists solely of one type of atom and cannot be broken down.
    • A mixture can be distinguished by its ability to be separated into basic parts through physical means.
    • An example of a homogeneous mixture is vinegar, with uniformly distributed components.
    • An experiment using a laser light can determine that Sample 2 is a colloid because it shows the Tyndall Effect, indicating particle dispersion.
    • Suspensions consist of larger particles that can settle over time and differ from solutions and colloids.
