Yes, aluminium is formed from metallic bonding. In metals like aluminium, the atoms are arranged in a lattice structure, which allows the outer electrons to move freely. This arrangement creates a ‘sea of electrons’ that are not associated with any one particular atom, which is the hallmark of metallic bonding.
In the case of aluminium, each atom donates its three outer electrons to this electron sea, which results in a strong attraction between the positively charged aluminium ions and the negatively charged electrons. This bond is what gives aluminium its characteristic properties, such as conductivity, malleability, and ductility.
Moreover, the ability of aluminium to maintain these metallic bonds at room temperature contributes to its stability and strength, making it a widely used material in various applications, from construction to packaging.
