4. Chemical Bonding and Molecular Structure

Chemical bonding is fundamental to the stability of molecules and compounds, resulting from the forces that hold atoms together. Key to understanding bonding is the octet rule, which dictates that atoms tend to fill their outer electron shells for stability. This chapter delves into the types of chemical bonds, including ionic and covalent bonds, their formation, and the properties of compounds formed through these bonds.

    Chemical Bonding And Molecular Structure

    Chemical bonding is the interaction that holds atoms together, leading to stable molecules through configurations like ionic and covalent bonding.

    Learning Practice

  • 4.1

    Introduction To Chemical Bonding

    Chemical bonding is the interaction that holds atoms together in compounds, vital for achieving stability in atomic structures.

    Learning Practice

  • 4.2

    Octet Rule

    The octet rule states that atoms tend to bond in ways that each atom has eight electrons in its valence shell, achieving stability similar to noble gases.

  • 4.3

    Types Of Chemical Bonds

    This section outlines the two primary types of chemical bonds: ionic and covalent, highlighting their formation processes and characteristics.

    Learning Practice

  • 4.3.1

    Ionic Bond (Electrovalent Bond)

    Ionic bonds form through the transfer of electrons between metals and non-metals, resulting in the formation of cations and anions.

    Learning Practice

  • 4.3.2

    Covalent Bond

    Covalent bonds are formed by the sharing of electrons between two non-metals, allowing them to achieve a stable electronic configuration.
