What is the category of aluminum on the periodic table? What is its phase?
Aluminum is a ductile and malleable metal. Although it has some unusual properties that might make it seem metalloid, it is not a metalloid because, on the periodic table, it lies along the line that differentiates between metals, nonmetals, and metalloids. You can tell by looking at the color categories, or the bold line on the table that it is in the metal category.
