In Schottky defect the difference in size between cation and anion is small. Frenkel defect contains ionic crystals where the anion is larger than the cation. Both anion and cation leave the solid crystal. Usually the smaller ion cation leaves its original lattice structure. Atoms permanently leave the crystal.

Density, mass of a unit volume of a material substance. Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... Density can also be expressed as kilograms per cubic metre (in MKS or SI units).

The commutative, associative, and distributive properties help you rewrite a complicated algebraic expression into one that is easier to deal with. When you rewrite an expression by a commutative property, you change the order of the numbers being added or multiplied. For that reason, it is important to understand the difference between the two. The commutative property concerns the order of certain mathematical operations. ... The associative property, on the other hand, concerns the grouping of elements in an operation. This can be shown by the equation (a + b) + c = a + (b + c).

The gold leaf electroscope is an instrument for detecting and measuring static electricity or voltage.
Apparatus:
A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate. This arrangement is insulated from the body of the instrument with an outer cover. A glass front allows you to watch the behaviour of the leaf.
Working:
The electroscope detects charge in the following way:
- A charged object is brought in contact with the open end of the wire. The charges are transferred via the wire which is a good conductor of electricity.
- The gold leaf plates also get charged and since they are similarly charged, they repel and move away from each other.
- This confirms the presence of charge on the body.
Grounding / Discharging
If the charged body was brought close to the electroscope and then, we simultaneously touch the metal plates with our hand, then this would cause the charges to flow through your body (our body is a good conductor of electricity) to the ground. This is called grounding.

Schottky defect is a type of point defect or imperfection in solids which is caused by a vacant position that is generated in a crystal lattice due to the atoms or ions moving out from the interior to the surface of the crystal.
A Frenkel defect is another form of a point defect which is created when an atom or cation leaves its original place in the lattice structure to create a vacancy while occupying another interstitial position within the solid crystal.
