Within a crystal there are point defects and line defects; point defects are missing or extra lattice points within the crystal lattice (vacancies or interstitials), line defects may be due to an 'extra' half lattice plane within the crystal. The end of a line defect plane is known as an edge dislocation, screw dislocations occur where part of a crystal is displaced over one lattice direction and is therefore twisted. Dislocation loops can occur where an edge and a screw dislocation intersect.

∙ 9y agoOne defect in crystals is a point defect which occur at or around a single lattice point. Another is a bulk defect where impurities cluster together.

∙ 13y agoDefects can occur as half-planes of atoms inside the crystal structure(dislocations). The boundaries between crystals can also be considered defects.

Rank the crystal lattice structures in order of decreasing efficiency of space in the structure?
Both face and hexagonal are the most efficient, so they are equal. Then it's body, then simple cube.

Why defects in crystals are called thermodynamic defects?
crystalline defets are present in a crystal due to the presence of impurities.

Which point defect lowers the density of crystals?
Any change in the configuration of the lattice of the crystal which causes the crystal structure to deviate from the ideal structure is called a crystal structure. It is of the following types - Point defects Line defects Surface defects volume defects
