Final answer:
Metallic bonding explains the common properties of metals, such as their ability to conduct electricity and heat, their shiny appearance, and their malleability. It involves the attraction between the positively charged atomic nuclei of metal atoms and the delocalized electrons in the metal.
Step-by-step explanation:
Metallic bonding is responsible for the common properties of metals. This type of bonding involves the attraction between the positively charged atomic nuclei of metal atoms and the delocalized electrons in the metal. The delocalized electrons are free to move throughout the metallic crystal, which allows metals to conduct electricity and heat well. The metallic bond also provides metals with their shiny appearance and the ability to be hammered into sheets and pulled into wires.
