    Study Notes

    Ionic Bonds

    • Formed through the transfer of electrons from one atom to another, resulting in charged ions.
    • Characterized by the attraction between positively and negatively charged ions.

    Covalent Bonds

    • Occur when atoms share electrons, allowing them to attain stability.
    • Shared electrons can be in single, double, or triple bonds based on how many pairs are exchanged.

    Metallic Bonds

    • Develop when metal atoms pool their electrons, enabling conductivity and malleability.
    • Results in a "sea of electrons" that facilitates sharing among many metal atoms.

    Alkali Metals

    • Comprise Group 1 of the periodic table, includes lithium, sodium, potassium, rubidium, cesium, and francium.
    • Highly reactive metals, especially with water, forming strong bases and hydrogen gas.

    Halogens

    • Found in Group 17 of the periodic table, consisting of fluorine, chlorine, bromine, iodine, and astatine.
    • Highly reactive nonmetals that readily form salts with alkali metals.

    Noble Gases

    • Reside in Group 18 of the periodic table, includes helium, neon, argon, krypton, xenon, and radon.
    • Known for their lack of reactivity due to a full valence electron shell.

    Electron Dot Diagram

    • A visual representation indicating the valence electrons of an atom as dots surrounding the element's symbol.
    • Helps understand bonding and electron configuration.

    Isotope

    • Variants of the same element that contain different numbers of neutrons, leading to different atomic masses (e.g., Carbon-12, Carbon-13, Carbon-14).
    • Isotopes can be stable or radioactive and have various applications in medicine and research.

    Common Chemical Compounds

    • Sodium Bromide (NaBr): Composed of sodium and bromide ions, commonly used in medical applications.
    • Lithium Oxide (Li₂O): An important compound used in ceramics and batteries.
    • Phosphate (PO₄³⁻): A polyatomic ion essential in biology and various biochemical processes.
    • Sodium Phosphate (Na₃PO₄): Used in food and industrial applications as a pH regulator.
    • Calcium Chloride (CaCl₂): Often used for de-icing roads and as a desiccant.
    • Magnesium Sulfide (MgS): Utilized in the production of ceramics and fertilizers.
    • Aluminum Fluoride (AlF₃): Important in aluminum production and catalyst in organic chemistry.
    • Potassium Nitrate (KNO₃): Historically used in fertilizers and food preservation.
    • Ammonium Chloride (NH₄Cl): Employed in fertilizers, food, and in some pharmaceutical products.

    Ionic Compounds

    • Typically solid at room temperature, indicative of strong ionic bonds.
    • Neutral overall charge; composed of positively charged cations and negatively charged anions.

    Molecular Bonds

    • Characterized by slight charges due to uneven sharing of electrons, can lead to polar molecules.

    Ions

    • Formed when an atom gains or loses electrons, leading to a charged particle (positive or negative).

    Types of Bonds

    • Single Bond: Involves the sharing of a single pair of electrons between two atoms.
    • Double Bond: Involves two pairs of electrons shared between two atoms, increasing bond strength.
    • Triple Bond: Involves sharing of three pairs of electrons, resulting in a strong connection between atoms.
