What type of bonding is it that allows metals to conduct electricity freely?
Metallic bonds
Metallic bonds are the force of attraction between positive metal ions and the valence electrons that are constantly moving around them. The ions form a lattice-like structure held together by the metallic bonds. Metallic bonds explain why metals can conduct electricity and bend without breaking.

Why can metals can conduct electricity?
Metals conduct electricity by allowing free electrons to move between the atoms. These electrons are not associated with a single atom or covalent bond. Alloys, which are a combination of different metallic elements, tend to offer a lower level of thermal conductivity than pure metals.
Why do metals have metallic bonds?
Metallic bonds result from the electrostatic attraction between metal cations and delocalized electrons. The nature of metallic bonding accounts for many of the physical properties of metals, such as conductivity and malleability.
How do metallic bonds contribute to the luster of the metal?
When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals.
What holds metallic bonds together?
metallic bond, force that holds atoms together in a metallic substance. The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.
