What else can I help you with?
What is the maximum number of the Bravais lattices possible How will you account for the existence of the thousand of structure from these lattices?
14 Bravais lattices are known and 230 space groups.
What is Bravais lattices?
there are various ways of placing point in space such that all the points have identical suroundings. these are called Bravais lattices after the scientis Bravais(1848). There are 5 Bravais lattices in 2-D and 14 lattices in 3-D. the five 2-D Bravais lattices are as follows:- 1.oblique 2. square 3. Hexagonal 4. Primitive rectangular 5. Lentred rectangular
Why is end- centered tetragonal bravais lattice not possible?
An end-centered tetragonal Bravais lattice cannot exist because it would violate the constraints of translational symmetry required for a Bravais lattice. In a tetragonal lattice, the unit cell must have four sides of equal length and right angles, which cannot be maintained if an end-centered arrangement is introduced.
How many bravais lattices exist?
There are 14 Bravais lattices in 3D space, which are categorized into 7 crystal systems based on the lattice parameters and symmetry. Each lattice type represents a unique way in which points can be arranged in space to form a crystal structure.
What is crystallattice?
When the crystal systems are combined with the various possible lattice centerings, we arrive at the Bravais lattices. They describe the geometric arrangement of the lattice points, and thereby the translational symmetry of the crystal. In three dimensions, there are 14 unique Bravais lattices which are distinct from one another in the translational symmetry they contain. All crystalline materials recognized until now (not including quasicrystals) fit in one of these arrangements. The fourteen three-dimensional lattices, classified by crystal system, are shown to the right. The Bravais lattices are sometimes referred to as space lattices.=The crystal structure consists of the same group of atoms, the basis, positioned around each and every lattice point. This group of atoms therefore repeats indefinitely in three dimensions according to the arrangement of one of the 14 Bravais lattices. The characteristic rotation and mirror symmetries of the group of atoms, or unit cell, is described by its crystallographic point group.=
Why Bravais lattices are 14 in number?
Bravais lattices are classified based on their lattice symmetries, leading to 14 possible combinations of translational and rotational symmetries. These 14 Bravais lattices represent all possible ways in which a lattice can be arranged in 3D space while maintaining translational periodicity. Each Bravais lattice has unique characteristics that define its geometric arrangement.

How many kinds of space lattices are present in a crystal?
There are 14 types of space lattices known as Bravais lattices which can fully describe the infinite repeating pattern in a crystal structure. These lattices are classified based on their symmetry and the arrangement of lattice points within the unit cell.

Is the side centered cube a bravais lattice?
Hi, No the side centered lattice is not a Bravais Lattice as the lattice doesn't look the same from an atom on the corner of the cube and an atom in the middle of a vertical edge of the cube (they don't even have the same number of neighbors). In fact, the side centered lattice is a simple cubic lattice with a basis of two atoms.
End centered orthorhombic is bravais lattice but tetragonal is not.why?

Describe briefly miller bravais indices?
If crystal planes and directions in hexagonal system are indexed using Miller Index, then the crystallography equivalent planes have indices which appear dissimilar. To overcome this, Miller-Bravais Index is used. In short meaning: Miller-Bravais index, used to identify a plane in a hexagonal or rhombohedral structure. The four digit of Miller-Bravais indices: (hkil). The i is always the negative of the sum of h and k. The h k l is determined similar like the Miller Index system.
