## Lattice

#### What exactly is a lattice?

A lattice is a mathematical structure that is studied in the fields of order theory and abstract algebra. It consists of a partially ordered set with a unique supremum (also known as a least upper bound or join) and a unique infimum for each pair of elements (also called a greatest lower bound or meet).

#### What exactly is the function of a lattice?

Although it is purely decorative, yet lattice is often used to protect climbing plants and vines that is used as a fence. Lattice sections are also used to edge flower beds, which surround for waste cans, or as skirting at the bottom of decks and porches to enhance the appearance of utility areas.

#### what are the various kinds of lattice?

A lattice system is a collection of lattices that share a common set of lattice point groups, which are subgroups of the arithmetic crystal classes. Triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic lattice systems are among the 14 Bravais lattices.

#### How can you figure out what the lattice structure is?

The relative sizes of the ions, as well as the ratio of the number of positive and negative ions in the compound, determine the structure of it. The anions, which are typically larger than the cations, and it usually arranged in a closest-packed sequence which includes simple ionic structures.

#### In BCC, how many lattice points are there?

It includes Gif 2 lattice point bcc and each unit cell in the body-centred cubic lattice that has two lattice points. If the atoms have a radius equal to one quarter of the unit cell’s body diagonal, the highest packing density occurs. The overall packing density is 68 percent in this case.

#### What is the concept of a lattice vector?

The edges of a unit cell in a lattice are represented by lattice vectors. They don’t have to be orthogonal to each other. Any vector in the lattice can be represented by a linear combination of lattice vectors with integral parameters.
