Is aluminum polar or non polar?

Although Aluminum Chloride (AlCl2) does have polar bonds, since there is a difference in electronegativity between the aluminum atom and chloride atom, the three dipoles cancel each other out, since there are no excessive electrons on the Aluminum. The Molecular and Electronic Geometry of AlCl2 are Trigonal Planar, so the bond angle will be 120 degrees. Long story short, the dipoles cancel each other out, causing the molecule as a whole to be non-polar.
