15 Examples of Metallic Bonding

The metal links They are a type of chemical union that occurs between atoms of the same metal. Through these bonds, very compact structures are achieved, since the nuclei of the atoms come together so much that they begin to share their valence electrons. For instance: bonds between aluminum atoms.

These valence electrons they 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 with the latter it may share certain aspects since the atoms involved share their electrons to some extent.

Properties of metallic bonds

In the metallic bond the electrons they move in a “cloud” around the atoms, which are closely bound together. Thus, the properties of metallic bonds justify many of the characteristic properties of metals, such as the solidity and hardness of their materials, their malleability and ductility, their good conduction of heat or electricity and even their luster, since they return almost all the light energy that hits them.

The atomic particles Joined by these links, they are usually organized three-dimensionally in hexagonal, cubic, or many other shapes. Mercury, for example, is liquid at room temperature, and atomic bonding occurs through different mechanisms and allows the formation of perfectly round drops of this metal.

Examples of metallic bonds

Metallic bonds are extremely common in the atomic world of metals, so any pure metallic element is a possible example:

  1. Links between silver (Ag) atoms.
  2. Bonds between gold (Au) atoms.
  3. Bonds between cadmium (Cd) atoms.
  4. Bonds between iron (Fe) atoms.
  5. Bonds between nickel (Ni) atoms.
  6. Bonds between zinc (Zn) atoms.
  7. Bonds between copper (Cu) atoms.
  8. Bonds between platinum (Pt) atoms.
  9. Bonds between aluminum atoms (Al).
  10. Bonds between gallium (Ga) atoms.
  11. Bonds between titanium (Ti) atoms.
  12. Bonds between palladium (Pd) atoms.
  13. Bonds between lead (Pb) atoms.
  14. Bonds between iridium atoms (Go).
  15. Bonds between cobalt (Co) atoms.
