    Study Notes

    Covalent Bonding Overview

    • Covalent bonding involves nonmetals or metalloids, typically found on the right side of the periodic table.
    • Common atoms involved in covalent bonds include hydrogen (H), carbon (C), nitrogen (N), oxygen (O), fluorine (F), phosphorus (P), and sulfur (S).

    Sharing in Covalent Bonding

    • Atoms share valence electrons to achieve a stable electronic configuration.
    • This sharing can involve single, double, or triple bonds depending on the number of shared electron pairs.

    Strength of Covalent Bonds

    • The strength of a covalent bond is determined by factors such as bond length, bond order, and the electronegativity of the atoms involved.
    • Shorter bonds are generally stronger due to overlapping atomic orbitals, while greater bond order (more shared pairs) also increases bond strength.

    Heteroatomic Molecules

    • Heteroatomic molecules consist of two or more different types of atoms.
    • Examples include water (H₂O) and carbon dioxide (CO₂), where varying elements contribute to unique properties.

    Achievements Through Covalent Bonding

    • Atoms achieve stability through covalent bonding by completing their valence shells, adhering to the octet rule for many.
    • This bonding facilitates the formation of complex structures and molecules, essential for life and various chemical processes.
