1.	MgAl_(2)O_(4), is found in the Spinal structure in which O^(2-) ions consititute CCP lattice, Mg^(2+) ions occupy 1/8th of the Tetrahedral voids and Al^(3+) ions occupy 1.2 of the Octahedral voids. Find the total +ve charge contained in one unit cell
Answer» `+7//4` electronic CHARGE `+6` electronic charge `+2` electronic charge `+8` electronic charge Solution :Total positive charge = Charge on `MG^(2+)` + Charge on `AL^(3+) = (1)/(8) xx 8 xx 2 + (1)/(2) xx 4 xx 3 = 8` electronic charge
