Answer» X2+can be an alkali earth metal cation say Ca2+ Ycan be phosphorus since it has +5 oxidation state, and Z can be oxygen with -2 oxidation state First Y and Z combine to form a complex anion YZ43-(net charge = 5 - 4x2 = -3) just like PO43-phosphate anion. Then X2+combines with YZ43-to form X3(YZ4)2. So it will be

Answer»

X2+can be an alkali earth metal cation say Ca2+

Ycan be phosphorus since it has +5 oxidation state, and Z can be oxygen with -2 oxidation state

First Y and Z combine to form a complex anion YZ43-(net charge = 5 - 4x2 = -3) just like PO43-phosphate anion.

Then X2+combines with YZ43-to form X3(YZ4)2. So it will be
