Its atomic number is 13. Hence 13 electrons. 2 in the K shell, 8 in the L shell and 3 will be in the M shell. Hence these three free electrons would make the aluminum trivalent.
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
I can think of two most common compounds for aluminum and they are alum, such as potassium aluminum sulfate (KAl(SO4)2·12H2O), and aluminum oxide (Al2O3). About 8.1% of the earth's crust is composed of aluminum.
Al is aluminum and its number 13 well it has 13 electrons the reason why they put +3 is that u lose 3 electrons to make a full valence shell and if its negative 2 for example the number would be number 8 and add 2 more electrons which makes it a full valence shell
+3
Aluminum typically forms the Al3+ ion. This ion loses three electrons to achieve a stable electron configuration.

The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
Aluminum (Al) follows the configuration of the noble gas before it, neon (Ne). Aluminum has 3 electrons in the 3rd level. Two of them are in the 3s subshell and the other is in the 3p subshell.[Ne]3s23p1

Here is the equation - Al3+ + 3e- -> Al
Aluminum has trivalent cation. It is Al3+
Aluminum has 13 electrons. To achieve a noble gas electron configuration like neon, aluminum needs to lose 3 electrons to have the same electron configuration as neon (10 electrons). This results in the formation of the Al3+ ion.
Al3+ is isoelectronic with neon with 10 electrons
AL has 3 more negative charges than positive ones
