If we look at groups 3A through 5A, we see two metal-loids for groups 4A (Si, Ge) and 5A (As, Sb), but only one metalloid in group 3A (B). To maintain a regular geometric pattern one might expect that aluminum would also be a metalloid, giving group 3A two metal-loids. What can you say about the metallic character of aluminum with respect to its neighbors based on its first ionization energy?
