Metallic bonds are a type of chemical bond that occurs between atoms of the same metal. Through these links, very compact structures are achieved, since the nuclei of the atoms come together so much that they begin to share their valence electrons. For example bonds between aluminum atoms.
These valence electrons remain around the set of nuclei as in a kind of cloud and the attraction between their negative charges and the positive charges of the nuclei is what holds the set firmly together.
In this way, the metallic bond is a strong and primary atomic bond, which can only occur between atoms of the same species and never as a form of the alloy ( mixture of metals). Nor should this type of bond be confused with ionic or covalent bonds, although it may share certain aspects with the latter since the atoms involved share their electrons to a certain extent.
Metallic bond Properties
The main characteristics or Properties of Metallic bonds are given in the list below:
- They exhibit electrostatic attraction because they are non-directional.
- They have a high metallic bond strength that is proportional to the cation charge.
- The interaction of the metal’s electrons with different wavelengths gives them a metallic gleam.
- Electrical power is transmitted through them.
- When electrons are heated, they gain a tremendous amount of kinetic energy and are able to migrate to cooler regions.
- They have energy dissipation and cation vibration characteristics when the shock happens.
