Okay so!
Electronic configuration of A = 2,8,2 = magnesium
Electronic configuration of B = 2,5 = nitrogen.
(a). A forms ion as : Mg²+ = A²+
B forms ion as : N³- = B³-
(b). 3Mg + N2 ➡️ Mg3N2
= 3A + B2 ➡️ A3B2.
(c). On electrolysis,
A (that is a cation) is obtained on cathode.
B (an anion) is obtained at anode.

ThaNku so much, but i wanted to ask how did u come to know that A is Mg , I mean it can be Beryllium or calcium or some other element...
Since atomic number = 12, it can only be magnesium. No two elements in the whole periodic table can have the same atomic number.
