Which of the following statements is NOT true about Schottky defect?

Which of the following statements is NOT true about Schottky defect?
  1. The electrical neutrality of the compound is not preserved.
  2. It occurs in ionic compound with sizes of cation and anion almost equal.
  3. The ions of ionic compound must have high co-ordination number.
  4. The density of substance decrease.

Solution

In a Schottky defect, an equal number of positive and negative ions are missing from their lattice sites, so the crystal remains electrically neutral
