Because aluminum takes forever to write. It's at least four times as easy to write Al.
It is listed in the Periodic Table and other lists of elements. (Aluminum is also called aluminium.)
The aluminum ion is lacking three electrons compared with the neutral atom. Thus, it is represented by Al3+. Note that aluminum can for other ions in conjunction with other elements, which are represented differently.

Aluminum's atomic symbol: Al Aluminum's ionic symbol: Al3+
Aluminum (Al) is a +3 metal, and nitrate (NO3) is a -1 polyatomic ion. In order to cancel out the charges, you need 3 nitrates for every 1 aluminum, so the correct formula is Al(NO3)3.
The element with the atomic number 13 is aluminum.
