Question

what is the nature of a bond between aluminum and chlorine which results in a very large difference in electronegativity? hint: begin by identifying al and cl each as metal or non - metal. ionic polar covalent metallic nonpolar covalent

Explanation:

Aluminum (Al) is a metal and chlorine (Cl) is a non - metal. Ionic bonds typically form between metals and non - metals. A large difference in electronegativity (as in this case) also favors the formation of an ionic bond. In an ionic bond, electrons are transferred from the metal (Al) to the non - metal (Cl).
Polar covalent bonds form between non - metals with a moderate difference in electronegativity. Metallic bonds are between metal atoms. Nonpolar covalent bonds form between non - metals with little or no difference in electronegativity.

Answer:

Ionic
