Metallic bonds are a type of chemical bond found in metals, where atoms share their outermost electrons freely. This creates a "sea of electrons" that allows the metal atoms to slide past each other, giving metals their characteristic properties like malleability and conductivity. For example, when you hammer a piece of copper, it can be shaped without breaking because the metallic bonds allow the atoms to rearrange easily. In addition to being malleable, metals are also good conductors of electricity and heat. The free-moving electrons in the metallic bond enable them to carry electric current efficiently. This is why metals like aluminum and gold are commonly used in electrical wiring and electronic devices.
