ANSWER : Metallic bonding is a type of chemical bonding that occurs between metal atoms. It involves the sharing of valence electrons between metal atoms, resulting in a sea of electrons that surrounds a lattice of positively charged metal ions.
Two common properties of metals are malleability and conductivity. Malleability refers to the ability of a metal to be shaped into thin sheets without breaking, while conductivity refers to the ability of a metal to conduct electricity and heat.
Metallic bonding produces these properties because the sea of delocalized electrons is free to move throughout the lattice of metal ions. When a force is applied to a metal, the ions in the lattice can slide past each other, facilitated by the movement of these electrons. This ability to move and slide past each other is what gives metals their malleability.
Similarly, the delocalized electrons are able to carry an electric current through the metal lattice. As electrons move through the metal lattice, they collide with the metal ions, transferring energy and producing heat. This transfer of energy is what gives metals their high thermal conductivity. In addition, the delocalized electrons are also able to transfer electrical charge through the metal lattice, resulting in the high electrical conductivity observed in metals.
In summary, metallic bonding produces the properties of malleability and conductivity in metals by creating a sea of delocalized electrons that can move freely throughout the lattice of metal ions, allowing for the movement of ions and the transfer of energy and electrical charge.
