What is difference between basis and lattice?
A lattice is a hypothetical regular and periodic arrangement of points in space. It is used to describe the structure of a crystal. A basis is a collection of atoms in particular fixed arrangement in space.
What is a lattice basis?
The basis is the arrangement of atoms associated with each lattice point. Sometimes there is only one atom per lattice point – a monatomic lattice – but often there are more.
What are primitive basis vectors?
Primitive lattice vectors are the shortest lattice vectors possible. Three of them span the lattice space. Unit cells are the space limited by a parallelepiped with edges that are three, non-coplanar lattice vectors. The primitive unit cell contains only one lattice point.
What is meant by basis in physics?
The crystal structure is formed by associating every lattice point with an assembly of atoms or molecules or ions, which are identical in composition, arrangement and orientation, is called as the basis.
How do lattice and basis form crystal structure?
The crystal structure is formed by associating every lattice point with an assembly of atoms or molecules or ions, which are identical in composition, arrangement and orientation, is called as the basis. The atomic arrangement in a crystal is called crystal structure.
What is lattice point in physics?
A Lattice point is the position in the unit cell or in a crystal where the probability of finding an atom or an ion is the highest. In other words, the atoms or ions occupy the lattice points in a crystalline solid.
What are basis atoms?
The basis consists of the two atoms: one atom is located in the corner of the unit cell and another atom in the center of the unit cell. The area of the conventional unit cell is larger by a factor of two than the area of the primitive unit cell.

What is primitive lattice?
A unit cell which has only one lattice point in the crystal are called primitive unit cells. This lattice point is present on the edges or corner of the unit cell.
