See more at bond Examples of metallic bondmetallic bond For metals, the chemical bond is called the metallicbond. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is because of the nature of the inter-atomic bonding, which is called a metallicbond. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In a metallicbond, any potential bonding electrons can easily be lost by the atoms in a crystalline structure.

The filled d-shells in these elements do not contribute much to the interatomic interactions, which are dominated by the s-electrons through metallic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Unlike in metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It is far more common for metal centers to have bonds to other atoms through metallic bonds or covalent bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These forces are weak, resulting in pairwise interatomic binding energies on the order of 1/100 those of covalent, ionic, and metallic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Its metallic bonds should also be very weak, possibly making it extremely volatile, like the noble gases, and potentially making it gaseous at room temperature. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In metallic bonds valence shell electrons are delocalized and shared between many atoms. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Its metallic bonds are similar to aromatic bonding in benzene, naphthalene, anthracene, ovalene, and so on. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is due to the way that metals bond chemically: metallic bonds (as opposed to covalent or ionic bonds) have free-moving electrons that transfer thermal energy rapidly through the metal. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. High degrees of ductility occur due to metallic bonds, which are found predominantly in metals and leads to the common perception that metals are ductile in general. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Therefore, the falling melting and boiling points of the alkali metals indicate that the strength of the metallic bonds of the alkali metals decreases down the group.
