Al3+
The electron configuration of aluminum (Al) is [Ne] 3s2 3p1
The electron dot configuration of Al is 3 dots, arranged as 2 dots on one side and 1 dot on the other. For S, the electron dot configuration is 6 dots, distributed on all four sides of the symbol.

Al3+
The element with this electron configuration is carbon (C). This electron configuration corresponds to 6 electrons, which is the atomic number of carbon.
There is no such thing as AI in chemistry. Al (with a lowercase L) is aluminum. It has the electron configuration 1s2 2s2 2p6 3s2 3p1
The electron configuration of 1s2 2s2 2p6 corresponds to a neutral atom of Neon (atomic number 10). A 3+ ion would have lost all its valence electrons, leaving behind a stable 1s2 2s2 2p6 configuration, giving it the electron configuration of a Neon ion.
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.
[Ne]3s23p1
An ion that comes from Al typically has a 3+ charge. This is because Aluminum (Al) loses three electrons to achieve a stable electron configuration, making it a cation with a 3+ charge.
The electron configuration of vanadium in its 3 oxidation state is Ar 3d2.
