Hello! I have a problem with AlCl3 as the bond between Al and Cl is not fully ionic and they have a covalent nature to them due to the respectively low difference in their electronegativities. Thats why they exist as dimers which are considered simple molecular substances. As a result, Al2Cl6 can sublime at atmospheric pressure. On the other hand, the bond in NaCl is fully ionic which makes its melting and boiling point much higher than those of the dimer AlCl3.

The idea of high charge density with the small ions being more stronger due to the close interactions of electrostatic forces but the larger ions having a weaker force in comparison confuses me could anyone explain maybe in visual terms how this is possible as I thought the larger ion having bigger charges, and what I would think larger electrostatic force interactions is wrong
