The type of bonding that occurs between atoms in a metallic substance is termed metallic bonding. In metallic bonding, electrons are shared freely among a lattice of metal cations, creating a "sea of electrons" that allows for conductivity and malleability. This type of bond is responsible for the characteristic properties of metals, such as ductility, electrical and thermal conductivity, and luster. Understanding metallic bonding is vital for material science and the development of metallic alloys.
