Aluminum fluoride exhibits ionic bonding. This type of bonding occurs when aluminum donates electrons to fluorine atoms, resulting in positively charged aluminum ions and negatively charged fluoride ions. These opposite charges create a strong electrostatic attraction, forming a stable ionic compound. Ionic compounds like aluminum fluoride typically have high melting and boiling points due to the strong forces between the ions. This robustness also translates to their ability to conduct electricity when melted or dissolved in water, as the ions are free to move and carry charge.
