A spinal is an important class of oxides consisting of two types of metal ions with oxides ions arranged in CCP layer. The normal spinal has one-eighth of the tetrahedral holes occupied by one type of metal ion and one-half of the octahedral holes occupied by another type of metal ion. such a spinal is formed by Zn^(2+), Al^(3+) and O^(2-) in the tetrahedral holes. if formula of the compound is Zn_(x)Al_(y) O_(z), then find the value of (x + y + z) ? The type of packing generated by type (I) is:

1.	A spinal is an important class of oxides consisting of two types of metal ions with oxides ions arranged in CCP layer. The normal spinal has one-eighth of the tetrahedral holes occupied by one type of metal ion and one-half of the octahedral holes occupied by another type of metal ion. such a spinal is formed by Zn^(2+), Al^(3+) and O^(2-) in the tetrahedral holes. if formula of the compound is Zn_(x)Al_(y) O_(z), then find the value of (x + y + z) ? The type of packing generated by type (I) is:
