Learn about the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species. Explore the historical evolution, qualitative models, and quantum mechanical approaches of chemical bonding theory.

Learn about the three main types of chemical bonds (ionic, covalent, and metallic) and how they form between atoms and ions. Also, discover the weaker intermolecular bonds (hydrogen bonds) and the differences between single, double, and triple bonds.

Learn about the formation and characteristics of chemical bonds between atoms, molecules and ions. Explore the theories of Lewis and Kossel, the types of chemical bonds (ionic, covalent, hydrogen and polar) and the examples of each type.

Learn about ionic and covalent bonding models, and how they explain the formation and properties of compounds. See examples of ionic and covalent bonds, such as sodium chloride and hydrogen molecule ion.

Learn about the three idealized types of chemical bonding: ionic, covalent and metallic, and how they relate to the properties of materials. Explore the common features of chemical bonding, such as energy, stability and bond distance.

Chemical bonds hold molecules together and create temporary connections that are essential to life. Types of chemical bonds including covalent, ionic, and hydrogen bonds and London dispersion forces.

Learn the basics of chemical bonding, such as atomic structure, Lewis diagrams, and octet rule. See examples of molecular compounds, ions, and exceptions to the octet rule.

Learn about the two main types of chemical bonds: ionic and covalent, and how they form molecules and compounds. Explore the Lewis dot structures, formal charge and VSEPR theory to understand the bonding patterns and properties of atoms and molecules.

chemical: A substance formed from two or more atoms that unite (bond) in a fixed proportion and structure. For example, water is a chemical made when two hydrogen atoms bond to one oxygen atom.
