What are the main types of chemical bonds?

The main types of chemical bonds are best defined as ionic, covalent, and metallic bonds. Ionic bonds form when there is a complete transfer of electrons from one atom to another, typically between a metal and a non-metal, resulting in the formation of charged ions that attract each other. Covalent bonds arise when two atoms share one or more pairs of electrons, often occurring between non-metals. Metallic bonds involve the sharing of free electrons among a lattice of metal atoms, which allows for properties like electrical conductivity and malleability.

These three types of bonds encompass the primary interactions that hold atoms together in compounds and materials. Understanding these bonds is crucial because they determine the physical and chemical properties of substances, influencing everything from boiling and melting points to electrical conductivity and solubility. The other choices incorrectly categorize types of bonds or include temporary interactions or forces, such as hydrogen bonds and van der Waals forces, which are not classified as primary types of chemical bonds.
