Which point defect in its crystal units alter the density of a solid ?

Schottky defect in crystals is observed when

Stoichiometric defects are of two types such as vacancy defects and interstitial defects. Which stoichiometric defect causes the decrease in density of solid?

Even crystals prepared with great care contains certain irregularities called crystal defects. Which stoichiometric defects causes decrease in density of the crystal .

Why does Frenkal defect not change the density of 'AgCl' crystals?

Assertion : Due to Frenkel defect, there is no change in the density of the crystalline solid. Reason : In Frenkel defect, no cation or anion leaves the crystal.

Due to Frenkel defect, the density of the ionic solids

' Interstitial defect decreases the density of a solid ''State whether this statement is true or false ?

Density of a unit cell is the same as the density of the substance. So, if the density of the substance is known, we can calculate the number of atoms or dimensions of the unit cell. The density of the unit cell is related to its formula mass (M), number of atoms per unit cell (z), edge length (a in cm), and Avogadro's constant N_(A) , as rho=(zxxM)/(a^(3)xxN_(A)) Q. A metal A (atomic mass=60) has a body-centred cubic crystal structure. the density of the metal is 4.2 g cm^(-3) . the volume of unit cell is

Teacher explained that due to a stoichiometric defect, the density of a crystal changes. Name the defect.

What is the effect of the presence of Schottky defects on the density of a crystal?
