Aluminum forms a cation with a 3+ charge, and the formula Al3+.
AL has 3 more negative charges than positive ones
Al3+ is isoelectronic with neon with 10 electrons
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
The correct formula for a compound combining Al³⁺ and S²⁻ is Al₂S₃. This is determined by balancing the charges of the ions so that they cancel out in the compound.
Al2S3 is the empirical formula
The ionic compound formed between Al^3+ and S^2- ions would have the formula Al2S3. This formula ensures that the positive and negative charges balance out in the compound, with two aluminum ions combining with three sulfide ions.
Al3 plus and N3 combine ionically -well neither species exist but aluminum and nitrogen combine to make aluminum nitride - AlN.

If you think to aluminium the ion is Al3+.
Yes - Al -----> Al3+ is the cation.
Na, Rb, Al3+, and S2- do not have a noble gas configuration as they do not have the complete outer shell of electrons like a noble gas. O2, Br, Ca, and O2- have noble gas configurations as they either have a complete outer shell of electrons or have gained/lost electrons to achieve a stable noble gas configuration.
Aluminum and sulfur can form an ionic bond, with aluminum losing three electrons to become Al3+ and sulfur gaining two electrons to become S2-. This results in the formation of the ionic compound aluminum sulfide (Al2S3).
