The document discusses different types of chemical bonds, including ionic bonds which result from electrostatic attraction between oppositely charged ions and covalent bonds which involve the sharing of electrons between atoms. Covalent bonds can be polar or nonpolar depending on electronegativity differences. The document also examines hydrogen bonding, van der Waals forces, and coordinate covalent bonds.

2. CHEMICAL BOND
• A chemical bond is a lasting attraction between atoms, ions or molecules that
enables the formation of chemical compounds. The bond may result from the
electrostatic force of attraction between oppositely charged ions as in
ionic bonds or through the sharing of electrons as in covalent bonds
