    Study Notes

    Metals Physical Properties

    • Metals are malleable and ductile, meaning they can be shaped and molded without breaking.
    • Metals are good conductors of heat and electricity, making them useful for various applications.
    • Metals are lustrous (shiny) and can be polished to maintain their appearance.
    • With the exception of mercury, metals are solids at room temperature.
    • Metals are tough and strong, making them suitable for construction and other uses.

    Metals Chemical Properties

    • Metals have a high density, which contributes to their strength and durability.
    • Metals form alloys with other metals or non-metals, allowing for the creation of new materials with unique properties.
    • Some metals react with air and corrode, requiring protection to maintain their integrity.
    • Metals are good conductors of heat and electricity, making them useful for various applications.

    Non-Metals Physical Properties

    • Non-metals are brittle (soft) and prone to breaking or shattering.
    • Non-metals are poor conductors of heat and electricity, limiting their use in certain applications.
    • Non-metals are non-lustrous (dull) and cannot be polished, with the exception of iodine.
    • Non-metals can exist as solids, liquids, or gases at room temperature, depending on the specific element.
    • Non-metals are neither tough nor strong, making them less suitable for construction and other uses.

    Non-Metals Chemical Properties

    • Non-metals are poor conductors of heat and electricity, unlike metals.
    • Non-metals are not ductile or malleable, and do not form alloys with other metals or non-metals.
    • Non-metals react more with metals compared to other non-metals.
    • Non-metals usually react with other non-metals at high temperatures.

    Oxides and Acids

    • Metals react with Oxygen to form basic oxides.
    • Non-metals react with Oxygen to form acidic or neutral oxides.
    • Most metals displace Hydrogen from dilute acids.
    • Non-metals do not react with dilute acids.

    Chemical Reactions

    • Substances that react are called reactants, and substances formed during a reaction are called products.

    Types of Chemical Reactions

    • There are six common types of chemical reactions.
    • The 5 primary types of chemical reactions are: combination, decomposition, displacement, double displacement, and precipitation reactions.

    Combination Reaction

    • A type of chemical reaction where two or more substances combine to form a new substance.

    Decomposition Reaction

    • A type of chemical reaction where a single substance breaks down into two or more simpler substances.

    Displacement Reaction

    • A type of chemical reaction where one element displaces another element from a compound.

    Double Displacement Reaction

    • A type of chemical reaction where two compounds exchange partners, forming two new compounds.
    • Example: BaCl2 + Na2SO4 → BaSO4 + 2NaCl

    Precipitation Reaction

    • A type of chemical reaction where a solid forms from a solution, usually as a result of mixing two solutions containing dissolved species.
    • Precipitation reactions often involve the formation of an insoluble ionic compound when two solutions containing soluble compounds are mixed.
    • Example: NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
