the periodic table is organized in a few ways. The elements in a column (up to down) are placed like that because they have the same amount of valence electrons (electrons in outer shell). The periodic table is also divided with metals on the right and covering most of the middle, metaloids to the right and gases to the far right of the table. Lastly because of Aluminum's physical and chemical properties it is with the other metals in about the center of the periodic table.

Aluminum is placed where it is on the Periodic Table based on its properties and characteristics. It belongs to group 13 and period 3, positioned between boron and gallium. This arrangement reflects its atomic structure and chemical behavior relative to other elements.
