(X), (Y), (Z) are elements of the third period. Oxide of (X) is ionic, that of (Y) is amphoteric and of (Z) a giant oxide molecule. (X), (Y) and (Z) will have atomic numbers in the order
  1. (X) < (Y) < (Z)
  2. (Z) < (Y) < (X)
  3. (X) < (Z) < (Y)
  4. (Y) < (X) < (Z)

Solution

For third period, "s" block will form ionic oxide, 13th group forms amphoteric oxide, and 14th group element will form giant oxide (SiO2) .
(X) < (Y) < (Z)
