Learn what chemical bonds are and how they hold atoms together in molecules. Explore the different types of chemical bonds, such as ionic, covalent, hydrogen, and metallic, with examples and diagrams. Learn about the different theories and concepts of chemical bonding , such as Kössel-Lewis approach, VSEPR theory, valence bond theory and molecular orbital theory. Understand the formation, geometry and properties of covalent and ionic bonds, and the role of valence electrons and orbitals. A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures . The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects. Chemical bonding is one of the most basic fundamentals of chemistry that explains other concepts such as molecules and reactions. Without it, scientists wouldn't be able to explain why atoms are …
