The electronegativity difference between Al and Cl is 1.55. This is borderline covalent/ionic. Aluminium trichloride solid has six coordinate aluminum atoms. As you heat it just before the melting point the conductivity rises then falls as the solid melts. In the molten state aluminum trichloride is dimeric, Al2Cl6, with four coordinate aluminium atoms.
The explanation is that the solid is more "ionic" and ions become mobile just before the melting point. At the melting point the neutral dimer is produced and the conductivity falls to zero. The bonding mode probably does not change in all of this
Alumin(i)um coheres by metallic bonding.
It is ionic bonding because Na is sodium which is a metal and Cl is chlorine which is a nonmetal. Ionic Bonding happens between nonmetals and nonmetals.
H-ClA single covalent bond between the hydrogen and the chlorine

Chlorine can be involved in both ionic and covalent bonding. As it is a chloride, I would believe it to be a ionic bond, as a covalent bond would state the number of chloride atoms, e.g. dichloride.
Ionic and covalent bonding involve electrons. Ionic bonding involves the loss and gain of electrons, form ions. Covalent bonding involves the sharing of electrons.
AlCl3 has simple covalent bonding because the aluminium cation is so small and highly charged (3+) that it has an extremely high charge density. This charge density distorts the electron cloud of the anions (Cl-) to such a large degree that the bonding is considered as covalent. This is why AlCl3 vapourises at room temperature, because it only has weak van der waal's intermolecular forces. Well I didn't write this! AlCl3 is a white crystalline solid with a melting point of 1920 It does NOT vapourise at room temperature! In the solid the aluminium has 6 chlorine atoms around it. The bonding is more ionic than covalent. At the melting point the structure changes to a dimer with a formula of Al2Cl6 with four chlorines around each aluminium atom. In this state the bonding is covalent.
Covalent bonding involves the sharing of electrons. Ionic bonding involves the transfer of electrons.
Covalent.
Caffeine is a covalent compound.
Aluminum chloride is an ionic compound because aluminum is a metal and chlorine is a nonmetal. When a metal and a nonmetal are combined they make up an ionic compound. Incorrect. Aluminium Chloride is covalent.
