The atoms in an alloy are held together by metallic bonds, which are found in solid metals like copper, iron, and aluminum. Metallic bonds are the strongest type of chemical bond.
The atoms in an alloy are held together by metallic bonds. Metallic bonds are found in solid metals like copper, iron, and aluminum, where each metal atom is bonded to several neighboring groups and bonding electrons are free to move throughout the 3-dimensional structure. This attraction between the metal ions and the sea of free-moving electrons is what holds the atoms together in a piece of metal. Metallic bonds are usually the strongest type of chemical bond.
