What noble has atom has the same electron configuration as aluminum sulfide

Answer 1

No ionic compound has a noble gas configuration, but...

Al³⁺ looks like Neon and S^2- looks like Argon. For the representative elements, the !A,IIA, IIIAs lose electrons and become positive +1, +2, and +3 respectively, going to the nearest noble gas configuration of 0 valence electrons. VA, VIA, VIIA acquire electrons and become -3, -2, and -1 respectively going to the nearest noble gas configuration having a full 8 (octet) electrons in their outer shell.
