    Study Notes

    Electron Dot Diagrams

    • Electron dot diagrams represent valence electrons as dots around the chemical symbol of an element.
    • These diagrams help visualize the number of valence electrons and predict bonding behavior.

    Electron Dot Diagram for Lithium

    • Lithium (Li) has 1 valence electron, represented as a single dot beside the symbol.

    Electron Dot Diagram for Oxygen

    • Oxygen (O) possesses 6 valence electrons, illustrated with 6 dots arranged around the symbol.

    Electron Dot Diagram for Neon

    • Neon (Ne) has a complete octet with 8 valence electrons, depicted as 8 dots evenly spaced around the symbol.

    Electron Dot Diagram for Magnesium

    • Magnesium (Mg) has 2 valence electrons, illustrated as 2 dots next to the symbol.

    Electron Dot Diagram for Iodine

    • Iodine (I) contains 7 valence electrons, represented by 7 dots around the symbol.

    Electron Dot Diagram for Boron

    • Boron (B) has 3 valence electrons, shown as 3 dots near the symbol.

    Electron Dot Diagram for Sulfur

    • Sulfur (S) has 6 valence electrons, visualized with 6 dots around its symbol.

    Electron Dot Diagram for Carbon

    • Carbon (C) possesses 4 valence electrons, illustrated with 4 dots surrounding the symbol.

    Electron Dot Diagram for Phosphorus

    • Phosphorus (P) has 5 valence electrons, represented by 5 dots around the symbol.

    Lewis Structures

    • Lewis structures depict the arrangement of electrons in a molecule, showing bond formation and lone pairs.

    Lewis Structure for PCl₃

    • Phosphorus (P) is centrally located, bonded to 3 chlorine (Cl) atoms, with 3 lone pairs around each Cl.

    Lewis Structure for CH₄

    • Carbon (C) is at the center, forming four single bonds with four hydrogen (H) atoms, completing its octet.

    Lewis Structure for CH₃Br

    • Carbon (C) has three single bonds with hydrogen (H) atoms and one single bond with bromine (Br), along with hydrogen's lone pairs.

    Lewis Structure for F₂O

    • Oxygen (O) is attached with two single bonds to two fluorine (F) atoms, and has 2 lone pairs, fulfilling the octet rule.

    Lewis Structure for IBr

    • Iodine (I) is shown with 6 lone electrons and a single bond to bromine (Br), which has 6 lone electrons.

    Lewis Structure for NH₂Cl

    • Nitrogen (N) is central, with two single N-H bonds and one N-Cl bond, while chlorine (Cl) has 6 lone electrons.

    Lewis Structure for CCl₂F₂

    • Carbon (C) has two single bonds to chlorine (Cl) and two to fluorine (F), with Cl and F nearing octet completion.

    Lewis Structure for CCl₄

    • Carbon (C) is bonded to four chlorine (Cl) atoms, completing the octet for both carbon and chlorine.

    Lewis Structure for ONCl

    • Oxygen (O) is double bonded to nitrogen (N), which has a single bond to chlorine (Cl). Nitrogen has 4 electrons and chlorine has 6 electrons.
