Metallic bond is a type of covalent bond (atoms share electrons) but in metallic bond the outermost electrons are free to wonder around the material. Metallic bonding is mostly non-polar, because even in alloys there is little difference among the electronegativities of the atoms participating in the bonding interaction (and, in pure elemental metals, none at all). These ions are surrounded by delocalized electrons, which are responsible for conductivity. (c) The metallic solid can be viewed as positive ions closely packed in a sea of valence electrons. Ionic bonding is the force of attraction between charged atoms or ions. Compare and contrast the two types of metal alloys. Examples of covalent bonds are diamond, carbon, silica, hydrogen gas, water, nitrogen gas, etc., whereas Silver, gold, nickel, copper, iron, etc. This is what makes metals malleable, what makes them excellent conductors of electricity and heat, but it also gives them characteristic sheen known as metallic luster and it also makes them opaque.
