Why is it not possible for aluminum atoms to form covalent bonds with other aluminum atoms?

The simple answer is it does! There are compounds aluminum dialkyls that contain an aluminum-aluminum bond. (quoted in Cotton and Wilkinson 6th edition) There are not many examples known- metal metal bonding is more common with gallium and indium. Gallium forms gallium- gallium bonds in the Ga2I62- anion and in some complexes. Indium also forms indium-indium bonds in for example the In2Br62- anion and recently a compound with a short chain of indium atoms was discovered. A detailed explanation of why the aluminum is different is complex and is due to a number of factors:
- the strength of the bond
- the thermodynamic stability of the comound in realtion to the decomposition products
- the "kinetic" stability of the compound e.g. how easily is it "attacked" by other molecules.

∙ 12y agoA number of theories have been developed to explain this. The one that provides the best explanation for observations is called the free electron theory. According to this theory, all of the valence electrons in a metal are available and shared by all of the atoms. This differs from sharing of electrons between individual atoms (covalent bonding), which cannot explain the behavior of metals.

What is the number of covalent bonds that are possible for atoms of silicon?
In a sufficiently oxidizing environment, silicon can form up to six covalent bonds, as in SiF6.
What are atoms bonded together with covalent bonds?
When atoms are bonded together with covalent bonds, the result is a molecule.
What type of bond do atoms share electrons?
In covalent bonds, electrons are shared. In ionic bonds, electrons are transferred.
The carbon atoms in organic molecules are bonded to other atoms by?
Carbon atoms are fixed into organic compounds in The Calvin Cycle.
What kind of atoms are covalent bonds?
Atoms do not have covalent bonds, they form them. A covalent bond is typically non-metal to non-metal, and hydrogen is considered a non meteal

What bonds does carbon atoms tend to form?
Carbon will almost always form bonds with other carbon atoms, and that is part of what makes it such a useful element.
What kind of bonds hold together atoms in a molecule?
The bonds are ionic or covalent.
What are the covalent bonds?
Covalent bonds are formed between atoms by sharing electrons between them.
